Purpose
To evaluate the effects of the degree of ethiodized oil accumulation achieved by transarterial chemoembolization followed by radiofrequency (RF) ablation on the treatment efficacy for a single intermediate-sized hepatocellular carcinoma (HCC).Materials and Methods
A total of 153 consecutive patients who underwent chemoembolization and RF ablation for a single intermediate-sized HCC (2–5 cm) were included. On the basis of the degree of ethiodized oil accumulation in HCC on cone-beam CT images, patients who underwent chemoembolization and RF ablation were classified into 2 groups: compact accumulation (≥ 75%) and noncompact accumulation (< 75%). The rates of cumulative local tumor progression (LTP), disease-free survival (DFS), and overall survival (OS) were compared between groups.Results
Of the 153 patients, 89 were classified into the compact ethiodized oil accumulation group and 64 in the noncompact ethiodized oil accumulation group. There were no significant differences in patient demographic or HCC characteristics between groups except for the incidence of liver cirrhosis (P = .038) and the tumor margin morphology (P = .008). The cumulative LTP rate was significantly lower in the compact accumulation group than in the noncompact accumulation group (P = .013). There were no significant differences in the incidences of complications, DFS rates (P = .055), or OS rates (P = .184).Conclusions
The degree of ethiodized oil accumulation does not play a role in decreasing the OS or DFS rate after chemoembolization and RF ablation for intermediate-sized HCC; however, it may contribute to reducing the rate of LTP. 相似文献2.

Purpose
To compare liver resection (LR) with single-step, balloon-occluded radiofrequency (RF) ablation plus drug-eluting embolics transarterial chemoembolization in cirrhotic patients with single hepatocellular carcinoma (HCC) ≥ 3 cm.Materials and Methods
From 2010 to 2014, 25 patients with compensated cirrhosis and single HCC ≥ 3 cm (median size 4.5 cm; range, 3.0–6.8 cm) not suitable for LR or liver transplantation were treated with RF ablation plus transarterial chemoembolization in a prospective observational single-center pilot study; all patients had complete tumor necrosis after treatment. A retrospective control group included 29 patients (median HCC size 4.0 cm; range, 3.0–7.4 cm) who underwent LR. RF ablation plus transarterial chemoembolization group included more patients with severe portal hypertension (65.5% vs 35.0%, P = .017). Primary endpoints were overall survival (OS) and tumor recurrence (TR) rates.Results
One death and 1 major complication (4%) were observed in LR group. No major complications were reported in RF ablation plus transarterial chemoembolization group (P = .463). OS rates at 1 and 3 years were 91.8% and 79.3% in LR group and 89.4% and 48.2% in RF ablation plus transarterial chemoembolization group (P = 0.117). TR rates at 1 and 3 years were 29.5% and 45.0% in LR group and 42.4% and 76.0% in RF ablation plus transarterial chemoembolization group (P = .034). Local tumor progression (LTP) rates at 3 years were significantly lower in LR group (21.8% vs 58.1%, P = .005). Similar results were found in patients with HCC ≤ 5 cm (TR rates 35.4% vs 75.1%, P = .016; LTP 16.0% vs 55.7%, P = .013).Conclusions
LR achieved lower TR and LTP rates than RF ablation plus transarterial chemoembolization, but 3-years OS rates were not statistically different between the 2 groups. RF ablation plus transarterial chemoembolization is an effective treatment option in patients with compensated cirrhosis and solitary HCC ≥ 3 cm unsuitable for LR. 相似文献3.

Purpose
To compare therapeutic outcomes of radiofrequency (RF) ablation combined with transcatheter arterial chemoembolization vs surgical resection (SR) for single 2–3 cm hepatocellular carcinoma (HCC).Materials and Methods
Seventy patients underwent combined chemoembolization/RF ablation therapy and 84 underwent SR. Local tumor progression (LTP), intrahepatic distant recurrence (IDR), disease-free survival (DFS), and overall survival (OS) rates, as well as major complications and duration of hospital stay, were compared between groups before and after propensity-score matching.Results
LTP and IDR had developed in 9 (12.9%) and 24 (34.3%) patients in the combined treatment group and in 7 (8.3%) and 24 (28.6%) patients in the SR group (P = .262 and P = .252, respectively). The 1-, 3-, 4-, and 5-year DFS rates were similar between groups (82.6%, 53.2%, 53.2%, and 37.6%, respectively, vs 84.5%, 63.6%, 59.2%, and 52.1%, respectively; P = .278), and 1-, 3-, 4-, and 5-year OS rates were also comparable (94.2%, 81.2%, 74.1%, and 59.4%, respectively, vs 95.2%, 86.3%, 84.0%, and 80.3%, respectively; P = .081). After matching (n = 98), LTP, IDR, DFS, and OS rates were still similar (P = .725, P = .826, P = .484, and P = .578, respectively). Major complication rate was not significantly different (2.9% vs. 6.0%; P = .596); however, after matching, major complication rate was higher in SR group (2.0% vs. 6.1%; P < .001). Hospital stays were significantly longer in the SR group (16.6 ± 6.7 d vs 8.5 ± 4.1 d; P < .001).Conclusions
Before and after matching, there were no significant differences in long-term therapeutic outcomes between combined chemoembolization/RF ablation and SR groups. Therefore, combined chemoembolization/RF ablation therapy may be an alternative treatment for single 2–3 cm HCCs. 相似文献4.

Purpose
To assess the safety and efficacy of single-session transarterial embolization and radiofrequency (RF) ablation for hepatic tumors with the use of needle navigation software.Materials and Methods
Retrospective analysis was conducted of 24 patients with liver cancer undergoing embolization followed by RF ablation between May 2014 and August 2017. Twelve patients each underwent (i) embolization and computed tomography (CT)–guided RF ablation during different sessions (group 1) and (ii) embolization followed by RF ablation with cone-beam CT and Needle Assist software in 1 session (group 2). Median age (70.5 y [range, 58–78 y] vs 70.5 y [range, 50–82 y]; P = .76) and performance status (0/1) were comparable between groups. Median tumor size was significantly larger in group 2 (2 cm [range, 1.0–7.3 cm] vs 3.2 cm [range, 1.1–9.6 cm]; P < .03). Procedure time, effective dose, and number of scans were examined. Efficacy was assessed by modified Response Evaluation Criteria In Solid Tumors after 1 month. Safety was assessed by Society of Interventional Radiology adverse event classification.Results
Group 1 had a mean of 8.5 CT scans, vs a mean of 5.0 cone-beam CT scans in group 2 (P < .001). Median procedure times were 110 min in group 1 and 199.5 min in group 2 (P < .001). Median effective doses were 68.8 mSv in group 1 and 55.4 mSv in group 2 (P = .38). There was no difference in complete response between groups (66.7% vs 63.6%; P = 1).Conclusions
Transarterial embolization followed by RF ablation with cone-beam CT and needle guidance software in a single session seems to be safe and effective. 相似文献5.

Purpose
To evaluate efficacy of cone-beam CT–based liver perfusion mapping obtained immediately following conventional transarterial chemoembolization of hepatocellular carcinoma (HCC) for assessing tumor vascularity, technical success of chemoembolization, and treatment response.Materials and Methods
From July 2015 to June 2016, 35 patients with 57 HCCs who underwent cone-beam CT with post-processing software via conventional transarterial chemoembolization for HCC and follow-up examination were included. Three reviewers evaluated technical success on angiography, unenhanced cone-beam CT, contrast-enhanced cone-beam CT, and cone-beam CT–based liver perfusion mapping after transarterial chemoembolization per tumor and per patient. Parenchymal blood volume (PBV) was measured. Treatment response was determined on follow-up CT, MR imaging, or histopathology according to modified Response Evaluation Criteria In Solid Tumors. Diagnostic performance for detection of a viable tumor was evaluated using multiple logistic regression with C-statistics.Results
Treatment response was 38, 17, 2, and 0 for complete response, partial response, stable disease, and progressive disease per tumor and 18, 15, 2, and 0 per patient. In multiple logistic regression, unenhanced cone-beam CT, contrast-enhanced cone-beam CT, cone-beam CT–based liver perfusion mapping, mean value of PBV, and maximum value of PBV of tumor were significant in response assessment for per tumor and per patient (per tumor, all P < .001; per patient, P = .015, P = .001, P < .001, P = .020, and P = .032). Mean value of PBV of tumor was excellent for evaluating technical success with the highest C-statistic (0.880 and 0.920 for per tumor and per patient), followed by that of visual assessment of cone-beam CT–based liver perfusion mapping (0.864 and 0.908).Conclusions
Cone-beam CT–based liver perfusion mapping provided reliable images to evaluate technical success after transarterial chemoembolization of HCC by qualitative visual assessment and quantitative perfusion values. 相似文献6.

Purpose
To compare treatment with hepatic arterial infusion of chemotherapy (HAIC) in patients with advanced hepatocellular carcinoma (HCC) with both extrahepatic spread (EHS) and intrahepatic tumor and patients with intrahepatic tumor only.Materials and Methods
This single-center retrospective study comprised 116 patients with advanced HCC with both intrahepatic tumor and EHS (EHS group; n = 50) or with intrahepatic tumor only (non-EHS group; n = 66) treated with HAIC including oxaliplatin, fluorouracil, and leucovorin between June 2014 and July 2016. Overall survival (OS) and radiologic responses to treatment were determined and compared between the 2 groups.Results
Both the objective response rate and the clinical benefit rate were higher in the non-EHS group than in the EHS group (37.9% vs 16% objective response rate, P = .010; 81.8% vs 62% clinical benefit rate, P = .017). Median OS was not statistically different between the 2 groups (14.8 months vs 9.8 months, P = .068). Subgroup analysis of OS found that patients with lung metastases survived for a shorter time (OS 7 months) than patients with other metastatic sites (P = .003) and patients free of metastases (P = .001).Conclusions
HAIC is a potential treatment option for advanced HCC with limited extrahepatic metastases in a population with hepatitis B virus infection. 相似文献7.

Purpose
To compare different imaging techniques (volume perfusion CT, cone-beam CT, and dynamic gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid–enhanced dynamic contrast–enhanced MR imaging with golden-angle radial sparse parallel MR imaging) in evaluation of transarterial chemoembolization of hepatocellular carcinoma (HCC) using radiopaque drug-eluting embolics (DEE).Materials and Methods
MR imaging and CT phantom investigation of radiopaque DEE was performed. In the clinical portion of the study, 13 patients (22 HCCs) were prospectively enrolled. All patients underwent cross-sectional imaging before and after transarterial chemoembolization using 100–300 μm radiopaque DEE. Qualitative assessment of images using a Likert scale was performed.Results
In the phantom study, CT-related beam-hardening artifacts were markedly visible at a concentration of 12% (v/v) radiopaque DEE; MR imaging demonstrated no significant detectable signal intensity changes. Imaging obtained before transarterial chemoembolization showed no significant difference regarding tumor depiction. Visualization of tumor feeding arteries was significantly improved with volume perfusion CT (P < .001) and cone-beam CT (P = .002) compared with MR imaging. Radiopaque DEE led to significant decrease in tumor depiction (P = .001) and significant increase of beam-hardening artifacts (P = .012) using volume perfusion CT before versus after transarterial chemoembolization. Greater residual arterial tumor enhancement was detected with MR imaging (10 HCCs) compared with volume perfusion CT (8 HCCs) and cone-beam CT (6 HCCs).Conclusions
Using radiopaque DEE, the imaging modalities provided comparable early treatment assessment. In HCCs with dense accumulation of radiopaque DEE, treatment assessment using volume perfusion CT or cone-beam CT may be impaired owing to resulting beam-hardening artifacts and contrast stasis. Dynamic contrast–enhanced MR imaging may add value in detection of residual arterial tumor enhancement. 相似文献8.

Purpose
To evaluate long-term outcomes of patients with hepatocellular carcinoma (HCC) who show a complete response (CR) vs non-CR on pretransplantation imaging studies or pathologic evaluation of liver explants after locoregional therapy (LRT) before liver transplantation.Materials and Methods
Patients listed for liver transplantation for HCC (March 1998 to December 2010) undergoing LRT with available multiphase MR/CT imaging before transplantation were included. Pathologic response was evaluated based on liver explant pathology. A total of 108 patients (17 women; 16%) met the inclusion criteria.Results
Radiologic CR was achieved in 65 patients (60%) vs non-CR in 43 (40%), and pathologic CR was achieved in 36 patients (33%) vs non-CR in 72 (67%). Mean 5-year overall survival (OS) from the time of listing and recurrence-free survival (RFS) after liver transplantation were significantly better for patients with pathologic CR vs non-CR on explant pathology (OS, 83.3% vs 65.2% [28% difference; P = .046]; RFS, 80.6% vs 62.5% [29% difference; P = .045]). Mean 5-y OS and RFS were not significantly different between patients with radiologic CR or non-CR on pretransplantation imaging (OS, 75.4% vs 65.1% [P = .12]; RFS, 74% vs 62.8% [P = .17]).Conclusions
Achievement of a pathologic CR vs non-CR in response to LRT before liver transplantation for HCC is associated with improved OS from time of listing and improved RFS after liver transplantation. However, current imaging paradigms fall short of accurate delineation of response to LRT, resulting in poor correlation of outcomes between pathologic and radiologic CR. 相似文献9.

Purpose
To construct the albumin-bilirubin (ALBI) grade and the Child-Turcotte-Pugh (CTP) score based on nomograms, as well as to develop an artificial neural network (ANN) to compare the prognostic performance of the 2 scores for hepatocellular carcinoma (HCC) that has undergone transarterial chemoembolization.Materials and Methods
This multicentric retrospective study included patients with HCC who underwent transarterial chemoembolization monotherapy as an initial treatment at 4 institutions between January 2008 and December 2016. In the training cohort, significant risk factors associated with overall survival (OS) were identified by univariate and multivariate analyses. The prognostic nomograms and ANN were established and then validated in 2 validation cohorts.Results
A total of 838 patients (548, 115, and 175 in the training cohort and validation cohorts 1 and 2, respectively) were included. The median OS was 10.4, 15.7, and 9.2 months in the training cohort and validation cohorts 1 and 2, respectively. In the training cohort, both ALBI grade and CTP score were identified as significant risk factors. The ALBI grade and CTP score based on nomograms were established separately and showed similar prognostic performance when assessed externally in validation cohorts (C-index in validation cohort 1: 0.823 vs 0.802, P = .417; in validation cohort 2: 0.716 vs 0.729, P = .793). ANN showed that ALBI grade had higher importance on survival prediction than CTP score.Conclusions
ALBI grade performs at least no worse than CTP score regarding survival prediction for HCC receiving transarterial chemoembolization. Considering the easy application, ALBI grade has the potential to be regarded as an alternative to CTP score. 相似文献10.

Purpose
To determine patient preference for transradial access (TRA) or transfemoral access (TFA) after experiencing both.Materials and Methods
A randomized controlled crossover trial was conducted at a single institution. Thirty patients with hepatocellular carcinoma undergoing mapping and transarterial radioembolization (TARE) were enrolled to experience 1 TRA and 1 TFA procedure each, with randomization of which access approach was experienced first. Surveys assessing pain and quality of life (QOL) were administered after each procedure. Access site preference was collected after completion of both procedures.Results
Twenty-two subjects (73.3%) preferred TRA, 4 (13.3%) preferred TFA, and 4 (13.3%) had no preference; 14 (46.7%) reported bruising after TRA, and 17 (53.3%) reported bruising after TFA. TRA was associated with significantly lower pain scores overall during the procedure, at the access site during the procedure, and in the recovery room compared with TFA (2.0 vs 2.9, P = .0046; 2.0 vs 3.0, P = .0004; 2.1 vs 2.9, P = .0357). Pain score after discharge was not significantly different (1.4 vs 1.5, P = .4235). QOL scores were not significantly different between TRA and TFA. No significant differences were found for fluoroscopy time, air kerma, dose-area product, or procedure time between TRA and TFA for either mapping (P = .1442, P = .5871, P = .6667, P = .6131) or radioembolization (P = .8574, P = .2344, P = .1119, P =.8474). For radioembolizations, TRA had significantly shorter recovery times compared with TFA (108 min vs 153 min, P = .0193).Conclusions
Patients exhibited a strong preference for TRA. With TRA, patients experienced less periprocedural pain and shorter recovery times without significant differences in radiation exposure or procedure length. 相似文献11.

Purpose
To determine if there is a correlation between intrahepatic tumor volume and future liver remnant (FLR) hypertrophy after portal vein embolization (PVE).Materials and Methods
Forty-four consecutive patients with hepatocellular carcinoma or metastatic colorectal cancer who underwent PVE from 2009 to 2017 and who had complete imaging follow-up were retrospectively reviewed. To maximize the accuracy of tumor volume measurements, 11 patients were excluded for having more than 5 intrahepatic tumors. Volumetric analyses of the patient livers before and after PVE, as well as pre-embolization intrahepatic tumor burden, were performed.Results
A significant inverse correlation was observed between tumor volume and FLR hypertrophy after PVE (Spearman ρ = -0.53, P = .002). Initial FLR volume was also inversely correlated with subsequent hypertrophy (P = .01). Fourteen patients received neoadjuvant chemotherapy 1 month prior to intervention. The number of chemotherapy cycles did not affect hypertrophy (P = .57). Patients with cirrhosis experienced less FLR hypertrophy than patients without cirrhosis (P = .02).Conclusions
Patients with large intrahepatic tumor burden may experience limited FLR hypertrophy. 相似文献12.

Purpose
To compare segmental radioembolization with segmental chemoembolization for localized, unresectable hepatocellular carcinoma (HCC) not amenable to ablation.Materials and Methods
In a single-center, retrospective study (2010–2015), 101 patients with 132 tumors underwent segmental radioembolization, and 77 patients with 103 tumors underwent segmental doxorubicin-based drug-eluting embolic or conventional chemoembolization. Patients receiving chemoembolization had worse performance status (Eastern Cooperative Oncology Group 0, 76% vs 56%; P = .003) and Child-Pugh class (class A, 65% vs 52%; P = .053); patients receiving radioembolization had larger tumors (32 mm vs 26 mm; P < .001), more infiltrative tumors (23% vs 9%; P = .01), and more vascular invasion (18% vs 1%; P < .001). Toxicity, tumor response, tumor progression, and survival were compared. Analyses were weighted using a propensity score (PS).Results
Toxicity rates were low, without significant differences. Index and overall complete response rates were 92% and 84% for radioembolization and 74% and 58% for chemoembolization (P = .001 and P < .001). Index tumor progression at 1 and 2 years was 8% and 15% in the radioembolization group and 30% and 42% in the chemoembolization group (P < .001). Median progression-free and overall survival were 564 days and 1,198 days in the radioembolization group and 271 days and 1,043 days in the chemoembolization group (PS-adjusted P = .002 and P = .35; censored by transplant PS-adjusted P < .001 and P = .064).Conclusions
Segmental radioembolization demonstrates higher complete response rates and local tumor control compared with segmental chemoembolization for HCC, with similar toxicity profiles. Superior progression-free survival was achieved. 相似文献13.

Purpose
The purpose of this study is to quantify the relationship between author gender and publication topic, as well as the impact of gender-related research.Methods
We reviewed all original research publications in Radiology, American Journal of Roentgenology, and Academic Radiology from 2011 through 2015. For each article, we recorded the gender of all authors and the last author H-index, years in practice, and academic rank. The total citations and citation rate (citations per year) were calculated for each article. Articles were categorized as gender-neutral, women’s health, or men’s health.Results
There were 1,934 publications involving 11,657 authors. Women represented 30% of first, 25% of last, and 28% of all authors. There were 1,596 (83%) gender-neutral, 276 (14%) women’s health, and 61 (3%) men’s health articles. Women’s health articles were associated with a female first (odds ratio [OR] = 5.0, P < .001) and last author (OR = 6.4, P < .001), as well as more female authors (male = 1.4, female = 3.6, P < .001). Men’s health articles were associated with a male first (OR = 2.6, P = .004) and last author (OR = 2.2, P = .03). There were significantly more citations for men’s (43.5 ± 54.9, P < .001) and women’s health (27.6 ± 37.5, P < .008) articles than gender-neutral articles (21.9 ± 28.9). Similarly, the article citation rate was higher for men’s (10.6 ± 11.3, P < .001) and women’s health (6.8 ± 8.5, P = .004) articles than gender-neutral publications (5.3 ± 7.0).Conclusion
Radiology researchers publish more often on topics related to their own gender. Furthermore, men’s and women’s health research generates more citations than gender-neutral research. 相似文献14.

Purpose
To compare perioperative and long-term outcomes of endovascular aneurysm repair (EVAR) with flared limbs (FLs) vs iliac branch devices (IBDs) for common iliac artery aneurysm to determine possible differences in outcome.Materials and Methods
From 2012 to 2017, all patients with standard EVAR with FLs and aortoiliac anatomy fit for implantation of IBDs were retrospectively selected and compared with patients with standard EVAR and IBDs. The study included 150 patients with 162 iliac treatments: 105 (65%) FLs and 57 (35%) IBDs. Iliac complications (ICs), including internal iliac artery (IIA) loss, limb thrombosis, and type 1b or type 3 endoleak, were considered at 30 days and in the follow-up period.Results
Procedural time and volume of contrast medium were significantly higher in IBD vs FL procedures (90 min ± 33 vs 70 min ± 25, P = .01; 130 mL ± 40 vs 80 mL ± 20, P = .01). Perioperative rate of ICs was similar between IBDs and FLs (0% vs 3.8% [4 IIA loss], P = .25). During 35-month median follow-up, there were 10 ICs, all in FLs group (4 IIA perioperative loss, 4 type 1b endoleak, 2 limb occlusion). By Kaplan-Meier analysis, survival free of ICs was significantly higher in IBD group after 4 years of follow-up (1 y 100% vs 96%, P = .36; 2 y 100% vs 94%, P = .14; 3 y 100% vs 91%, P = .07; 4 y 100% vs 87%, P = .03; 5 y 100% vs 78%, P = .02).Conclusions
IBDs and FLs have similar perioperative results. IBDs require longer procedural time and greater contrast medium volume; however, they are associated with lower ICs after 4 years of follow-up. 相似文献15.

Purpose
The aims of this study were to evaluate treatment responses and predictive factors for overall survival (OS) in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) treated with iodine-125 (125I) brachytherapy.Methods and Materials
Seventy-seven HCC patients with PVTT underwent 125I brachytherapy after transcatheter arterial chemoembolization. Clinical, laboratory, and radiological evaluation were performed before and after treatment, as well as at 4–6 weeks intervals for 7 years to assess the efficacy and toxicity of therapy. Treatment response was assessed using modified response evaluation criteria in solid tumors. OS and predictive factors for each subgroup were evaluated after treatment.Results
In total, 11 patients (14.29%) achieved complete response, and 41 patients (53.25%) achieved partial response. The response rate (complete response + partial response) was 67.53% (52/77). The median OS was 9 months. The multivariable Cox regression model indicated that post-treatment tumor size with PVTT (p = 0.016, hazard ratio [HR] = 1.889, 95% confidence interval [CI]: 1.127 to 3.166) and baseline hemoglobin (p = 0.013, HR=0.518, 95% CI: 0.308 to 0.872) and alkaline phosphatase (p = 0.002, HR=2.275, 95% CI: 1.338 to 3.868) levels were significant independent predictors of OS.Conclusions
125I brachytherapy results in favorable treatment responses in HCC patients with PVTT. Notably, post-treatment tumor size and baseline hemoglobin and alkaline phosphatase levels are significant independent predictive factors for OS and provide the most predictive information regarding OS. 相似文献16.

Purpose
To evaluate the influence of percutaneous cryoablation for renal cell carcinoma on function of the affected kidney.Materials and Methods
Between June 2016 and September 2017 at our institution, 12 inoperable patients underwent 15 cryoablation sessions for 17 small renal tumors. Of these, 9 patients who underwent 11 sessions of cryoablation were the focus of this study. For those patients, time-dependent changes in postoperative renal function were investigated by a retrospective review of clinical records. Evaluated were the estimated glomerular filtration rate (eGFR) and scintigraphy using 99m technetium-mercaptoacetyltriglycine (99mTc-MAG3) before and 1 week, 1–2 months, and more than 6 months after cryoablation.Results
Mean baseline eGFR was 76.88 ± 29.82 mL/min/1.73 m2 (mean ± standard deviation; range, 23.4–112.5). Mean eGFR 1 week, 1–2 months, and more than 6 months after cryoablation were 74.56 ± 26.68 mL/min/1.73 m2 (21.0–101.1), 69.5 ± 25.28 mL/min/1.73 m2 (24.1–105.6), and 75.08 ± 26.25 mL/min/1.73 m2 (29.0–107.3), respectively. Changes were statistically insignificant (P = .6044, P = .6699, and P = .9038, respectively). Regarding split renal function, the mean baseline contribution of the affected kidney determined by 99mTc-MAG3 was 47.27% ± 6.14 (38.8%–57.0%). Mean contributions of the affected kidney 1 week after, 1–2 months after, and more than 6 months after cryoablation were 44.40% ± 5.37 (38.3%–53.6%), 44.57% ± 6.52 (34.35%–55.0%), and 45.41% ± 7.77 (34.4%–56.5%), respectively. Differences from baseline were significant for the earliest 2 periods (P = .0473 and P = .0334, respectively) but not the later period (P = .2532).Conclusions
Results suggested that total renal function does not worsen after cryoablation; however, function of the affected kidney worsened after cryoablation but later partially recovered. 相似文献17.

Purpose
To compare survival outcome of radiofrequency (RF) ablation and surgical resection (SR) for treatment of hepatocellular carcinoma (HCC) ≤ 2 cm.Materials and Methods
In this retrospective study, patients from the US National Cancer Database with HCC ≤ 2 cm received RF ablation or SR as sole treatment. Overall survival (OS) was compared using log-rank test, multivariable Cox proportional hazard regression, and propensity score matched analysis.Results
Of 833 patients included, 620 received RF ablation and 213 received SR. The 1-, 3-, and 5-year OS rates were 90%, 64%, and 47% for RF ablation and 89%, 75%, and 62% for SR. On univariate analyses, patients who received SR had longer OS than patients who received RF ablation, but this did not achieve statistical significance (P = .113). On multivariate analyses, female sex (HR = 0.700; 95% CI, 0.501–0.979; P = .037), African American (HR = 0.611; 95% CI, 0.398–0.938; P = .024) and Asian ethnicity (HR = 0.427; 95% CI, 0.230–0.790; P = .007), and median income ≥ $48,000 (HR = 0.695; 95% CI, 0.518–0.932; P = .015) were associated with longer OS, whereas higher Model for End-stage Liver Disease (MELD) scores (HR = 1.023; 95% CI, 1.009–1.037; P = .001) were associated with shorter OS. After matching on age, sex, ethnicity, MELD score, and income, there was no significant difference in OS between the 2 treatment groups (log-rank P = .646).Conclusions
There was no significant difference in OS between RF ablation and SR in treatment of HCC measuring ≤ 2 cm. 相似文献18.

Purpose
To investigate the current state of gender diversity among invited coordinators at the Society of Interventional Radiology (SIR) Annual Scientific Meeting and to compare the academic productivity of female interventional radiologists to that of invited male coordinators.Materials and Methods
Faculty rosters for the SIR Annual Scientific Meetings from 2015 to 2017 were stratified by gender to quantify female representation among those asked to lead and coordinate podium sessions. To quantify academic productivity and merit, H-index, publications, and authorship by females over a 6-year period (2012–2017) were statistically compared to that of recurring male faculty.Results
From 2015 to 2017, women held 7.1% (9/126), 4.3%, (8/188), and 13.7% (27/197) of the available coordinator positions for podium sessions, with no representation at the plenary sessions, and subject matter expertise was concentrated in economics and education. Academic productivity of the top quartile of published female interventional radiologists was statistically similar to that of the invited male faculty (H-index P = .722; total publications P = .689; and authorship P = .662).Conclusions
This study found that senior men dominate the SIR Annual Scientific Meeting, with few women leading or coordinating the podium sessions, despite their established academic track record. 相似文献19.

Purpose
Americans with limited English proficiency (LEP) face significant barriers to health care that result in health disparities in the LEP population. LEP could delay an MRI, potentially increasing morbidity and mortality in the LEP population. This study compares the time to obtain a neurological MRI in English versus non-English language preference patients.Methods
24,219 unique patients at a single health system who underwent inpatient neurological MRI were included in the study. Bivariate and multivariate analyses were used to identify characteristics predictive of time to examination (TTE) from the set: patient-preferred language, gender, race, age, performing hospital, and order priority (routine versus stat).Results
Bivariate analysis showed a longer TTE is associated with increasing age category, non-English language preference, and routine priority. A multivariate analysis showed non-English language preference effect on TTE is reduced in magnitude and is no longer significant in a model that includes age group, priority, and hospital (P = .23, effect estimate = 4%, 95% CI: ?2.5%, 11.0%). Routine order priority (P < .0001) and increasing age (P < .0001) were associated with increased TTE. In a model that included interactions, the effect of language preference did not depend on order priority (P = .59) or age group (P = .11).Conclusion
There is no significant difference in the time to obtain a neurological MRI in English versus non-English language preference patients when age, order priority, and performing hospital are accounted for. This finding supports the effectiveness of the protocols and resources in place to support patients with LEP at the sponsoring health system. 相似文献20.
