Evaluation of transcatheter arterial embolization therapy on hepatocellular carcinomas using contrast-enhanced harmonic power Doppler sonography: comparison with CT,power Doppler sonography,and dynamic MRI

Purpose The aim of this study was to assess and compare the sensitivity of power Doppler sonography, contrast-enhanced sonography, plain computed tomography (CT), and dynamic magnetic resonance imaging (MRI) for detecting hepatocellular carcinoma (HCC) nodules incompletely treated with transcatheter arterial embolization (TAE). Methods A total of 63 unresectable HCC nodules were examined in this study. The HCCs were treated with TAE. All patients underwent plain CT, power Doppler sonography, contrast-enhanced harmonic power Doppler sonography, and dynamic MRI 1 week after TAE. The sensitivity of each modality to incompletely treated HCC nodules was compared. Detection of the residual viable HCC on angiography or tumor biopsy was regarded as the gold standard for the diagnosis of incomplete treatment. Results Twenty-four nodules (38%) were diagnosed as incompletely treated. The sensitivities of plain CT, power Doppler sonography, contrast-enhanced harmonic power Doppler sonography, and dynamic MRI to these incompletely treated nodules were 42% (10/24), 46% (11/24), 88% (21/24), and 79% (19/24), respectively. Eighty percent (19 nodules) of the 24 incompletely treated nodules were located within a depth of less than 8 cm. The sensitivities of plain CT, power Doppler sonography, contrast-enhanced harmonic power Doppler sonography, and dynamic MRI to these superficial incompletely treated nodules were 37% (7/19), 53% (10/19), 100% (19/19), and 74% (14/19), respectively. In contrast, the sensitivities of each modality to deeply located nodules were 60% (3/5), 20% (1/5), 40% (2/5), and 100% (5/5), respectively. Conclusion Plain CT and power Doppler sonography had a low sensitivity to HCC nodules incompletely treated with TAE. Except for those that were deeply located, contrast-enhanced harmonic sonography showed the highest sensitivity in detecting incompletely treated HCC nodules.     

CT联合MRI评估原发性肝癌患者的介入及分子靶向治疗效果

目的探讨CT及MRI评估原发性肝癌（HCC）患者介入及分子靶向治疗效果的价值。方法回顾性选取我院于2017年1月~2019年1月收治的80例中晚期HCC患者作为研究对象,患者均行肝动脉化疗栓塞术（TACE）治疗+索拉非尼治疗,3月后均行CT、MRI和数字减影血管造影（DSA）检查。比较CT联合MRI与单独CT检查HCC患者治疗后3月的临床有效例数、有效率,并以DSA检查结果为金标准,计算两种检查方法的敏感度、特异度、准确率和kappa值,并比较两种检查方法对患者治疗后的残余和复发病灶检出情况。结果经TACE+索拉非尼治疗后3月,DSA显示总目标病灶数由98个减少至86个,病灶明显缩小,临床疾病控制患者64例,无效患者16例,疾病控制率80.00%;共检出残留和复发病灶共82个,其中Ⅰ型、Ⅱ型、Ⅲ型、Ⅳ型碘油沉积残留和复发病灶数分别为9、18、42、17个。CT联合MRI检出患者治疗后Ⅱ型以及总碘油沉积残留、复发病灶个数均大于CT检查（P < 0.05）; CT联合MRI评估TACE+索拉非尼治疗HCC患者疗效的灵敏度95.31%高于单独CT检查的84.38%（P < 0.05）,且CT联合MRI评估临床疗效与DSA检查的Kappa值为0.809,且大于单独CT评估与DSA检查的Kappa值（0.605）。结论TACE+索拉非尼治疗HCC患者3月后具有较好的临床疗效,且相比单独CT检查,CT联合MRI更有利于患者治疗后残留和复发灶的检出,同时对于患者治疗后3月疗效的评估具有更高的灵敏度和应用价值。      

Comparison of ultrasound elastography, mammography, and sonography in the diagnosis of solid breast lesions.

OBJECTIVE: The purpose of this study was to evaluate the value of ultrasound elastography (UE) in differentiating benign versus malignant lesions in the breast and compare it with conventional sonography and mammography. METHODS: From September 2004 to May 2005, 296 solid lesions from 232 consecutive patients were diagnosed as benign or malignant by mammography and sonography and further analyzed with UE. The diagnostic results were compared with histopathologic findings. The sensitivity, specificity, accuracy, positive and negative predictive values, and false-positive and -negative rates were calculated for each modality and the combination of UE and sonography. RESULTS: Of 296 lesions, 87 were histologically malignant, and 209 were benign. Ultrasound elastography was the most specific (95.7%) and had the lowest false-positive rate (4.3%) of the 3 modalities. The accuracy (88.2%) and positive predictive value (87.1%) of UE were higher than those of sonography (72.6% and 52.5%, respectively). The sensitivity values, negative predictive values, and false negative rates of the 3 modalities had no differences. A combination of UE and sonography had the best sensitivity (89.7%) and accuracy (93.9%) and the lowest false-negative rate (9.2%). The specificity (95.7%) and positive predictive value (89.7%) of the combination were better, and the false-positive rate (4.3%) of the combination was lower than those of mammography and sonography. CONCLUSIONS: In a clinical trial with Chinese women, UE was superior to sonography and equal or superior to mammography in differentiating benign and malignant lesions in the breast. A combination of UE and sonography had the best results in detecting cancer and potentially could reduce unnecessary biopsy. Ultrasound elastography is a promising technique for evaluating breast lesions.

目的：评价超声造影谐频成像在原发性肝癌治疗后疗效判断方面的作用。方法：使用Levovist对27例33个肝癌结节治疗前后分别行超声造影能量多普勒谐频成像和灰阶谐频成像数字减影检查,结果与动态增强CT相比较。结果：以动态增强CT结果为金标准,治疗前33个肝癌结节,超声造影增强的阳性率为93．9％（31／33）;而对治疗后肝癌,能量多普勒成像显示肿瘤内血流信号的敏感性,特性和准确性均为100％,灰阶谐频成像数字减影则分别为93．9％、100％和96．8％,结论：超声造影谐频成像可以敏感而直观地显示治疗后肿瘤内残存的血流信号,即时评估肿瘤的治疗效果,创伤小,值得临床推广。     

Intraoperative sonography of hepatocellular carcinoma: Detection of lesions and validity in surgical resection

Eighty-six hepatocellular carcinomas (HCCs) in 67 patients were examined by intraoperative sonography. Sensitivity for detecting tumors with intraoperative sonography was compared with sonography, computed tomography (CT), hepatic angiography, and CT after intraarterial injection of iodized poppy-seed oil (Lipiodol-CT). The overall sensitivities were 76% with sonography, 86% with CT, 89% with angiography, 96% with Lipiodol-CT, and 98% with intraoperative sonography. The differences in sensitivity between intraoperative sonography and sonography (p < 0.01), CT (p < 0.01), and angiography (p < 0.05) were significant. In 35 lesions smaller than 2 cm, the sensitivities of Lipiodol-CT and intraoperative sonography were high (91 and 94%, respectively). In operating field, tumors were invisible in 36 (42%) and nonpalpable in 31 of 86 cases (36%). In 35 tumors smaller than 2 cm, invisible tumors were 66% and nonpalpable tumors were 63%. However, 84 of 86 cases (98%) could be localized with intraoperative sonography.These results suggest that intraoperative sonography is the final diagnostic imaging procedure before surgical resection of tumors and in cases of invisible and nonpalpable tumors in the operating field, this procedure is mandatory to improve surgical results.     

Assessment of the therapeutic response of hepatocellular carcinoma treated with transcatheter arterial chemoembolization: comparison of contrast-enhanced sonography and 3-phase computed tomography.

OBJECTIVE: The purpose of this study was to compare contrast-enhanced sonography with 3-phase computed tomography (CT) in assessing the therapeutic response of hepatocellular carcinomas (HCCs) treated with transcatheter arterial chemoembolization (TACE). METHODS: Twenty-nine nodular HCCs treated with TACE were examined with contrast-enhanced sonography, 3-phase helical CT, and conventional angiography. Contrast-enhanced sonographic and CT findings were interpreted separately and prospectively for the presence or absence of contrast enhancement in the treated HCCs. Conventional angiography served as the reference standard. RESULTS: Intratumoral enhancement was seen in 19 HCCs (61%) on contrast-enhanced sonography and 12 HCCs (39%) on CT. Enhancement patterns on sonography were blush in 8 (42%), branching in 2 (11%), nodular in 4 (21%), and stippled in 5 (26%). Of the 19 HCCs with intratumoral enhancement on contrast-enhanced sonography, 13 (68%) showed tumor staining on angiography. Of the 12 HCCs without intratumoral enhancement on sonography, 1 (8%) showed tumor staining on angiography. The sensitivity and specificity of contrast-enhanced sonography in depicting flow in HCCs treated with TACE were 93% and 65%, respectively. The sensitivity and specificity of 3-phase CT were 64% and 100%. CONCLUSIONS: Contrast-enhanced sonography is a more sensitive imaging method than 3-phase CT in depicting vascularity in HCCs treated with TACE.

Prenatal Diagnosis of Placenta Accreta

Objective. The purpose of this study was to compare the accuracy of transabdominal sonography and magnetic resonance imaging (MRI) for prenatal diagnosis of placenta accreta. Methods. A historical cohort study was undertaken at 3 institutions identifying women at risk for placenta accreta who had undergone both sonography and MRI prenatally. Sonographic and MRI findings were compared with the final diagnosis as determined at delivery and by pathologic examination. Results. Thirty‐two patients who had both sonography and MRI prenatally to evaluate for placenta accreta were identified. Of these, 15 had confirmation of placenta accreta at delivery. Sonography correctly identified the presence of placenta accreta in 14 of 15 patients (93% sensitivity; 95% confidence interval [CI], 80%–100%) and the absence of placenta accreta in 12 of 17 patients (71% specificity; 95% CI, 49%–93%). Magnetic resonance imaging correctly identified the presence of placenta accreta in 12 of 15 patients (80% sensitivity; 95% CI, 60%–100%) and the absence of placenta accreta in 11 of 17 patients (65% specificity; 95% CI, 42%–88%). In 7 of 32 cases, sonography and MRI had discordant diagnoses: sonography was correct in 5 cases, and MRI was correct in 2. There was no statistical difference in sensitivity (P = .25) or specificity (P = .5) between sonography and MRI. Conclusions. Both sonography and MRI have fairly good sensitivity for prenatal diagnosis of placenta accreta; however, specificity does not appear to be as good as reported in other studies. In the case of inconclusive findings with one imaging modality, the other modality may be useful for clarifying the diagnosis.     

Evaluation of posttreatment response of hepatocellular carcinoma: comparison of ultrasonography with second-generation ultrasound contrast agent and multidetector CT

We evaluated the ability of one-month follow-up contrast-enhanced ultrasound (CEUS) with second-generation contrast agent in monitoring radio frequency ablation (RFA) and transcatheter arterial chemoembolization (TACE) treatments of hepatocellular carcinoma (HCC). One-hundred forty-eight HCCs were studied using CEUS: 110 nodules were treated with RFA [41/110 RFA were performed using a pretreatment and an immediate postablation evaluation using CEUS (group 1); 69/110 using only US guidance (group 2)] and 38 nodules treated with TACE. For statistical analysis, McNemar test was used. Overall complete response was observed in 107/148 nodules (92/110 treated with RFA and 15/38 with TACE). A better rate of complete response was found in group 1 compared to group 2 (92.7% vs. 78.3%). In RFA treatment, CEUS showed a sensitivity of 83.3% and a specificity of 100% (diagnostic accuracy of 97%) using MDCT as reference standard with no statistical difference (p > 0.05). CEUS detected all cases of incomplete response in HCC treated with TACE using angiography as reference standard (diagnostic accuracy 100%). We recommend assessing residual intratumoral flow on CEUS during RFA procedure to determine the necessity of immediate additional treatment. In case of positive CEUS results, HCC treated with TACE should be considered still viable.     

Detection of recurrent hepatocellular carcinoma on post-operative surveillance: comparison of MDCT and gadoxetic acid-enhanced MRI

Objective

To compare the accuracy of multidetector computed tomography (MDCT) and gadoxetic acid-enhanced magnetic resonance imaging (MRI) for the detection of intrahepatic tumor recurrence after curative resection of hepatocellular carcinoma (HCC).

Materials and methods

Fifty-six patients who underwent MDCT and gadoxetic acid-enhanced MRI for postoperative surveillance after resection of HCC were retrospectively analyzed; 26 patients had a recurrence (36 lesions) and 30 patients did not. Recurrent HCCs were confirmed by histological examinations in two, typical dynamic imaging findings on CT and/or MRI in 28, and by demonstration of growth or tumor staining on angiography on six. Two reviewers graded the confidence for the presence of recurrence on CT and MRI, using a five-point scale. The jackknife free-response receiver operating characteristic method was used to compare diagnostic performance. The accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated.

Results

For 36 recurrent lesions, the figure of merit was significantly higher for MRI than MDCT for detecting recurrence for both reviewers (p < 0.005 for both reviewers). In lesion-by-lesion analysis, the sensitivity was significantly higher on MRI (100% for reviewer 1 and 97% for reviewer 2) than on MDCT (44.4% and 66.6%) for both reviewers (p < 0.005 for both reviewers). Also in patient-by-patient analysis, sensitivity was significantly higher on MRI (100% and 96.1%) than on MDCT (57.6% and 76.9%) for both reviewers (p < 0.05 for both reviewers).

Conclusion

Gadoxetic acid-enhanced MRI is superior to MDCT for detecting intrahepatic recurrence after curative resection of HCC.

Depth of myometrial invasion in endometrial cancer: preoperative assessment by transvaginal ultrasonography and magnetic resonance imaging.

Depth of myometrial invasion in endometrial cancer correlates with pelvic lymph node metastases and tumor recurrence. Thirty patients diagnosed as having FIGO stage I endometrial carcinoma on the basis of D&C were evaluated preoperatively by magnetic resonance imaging (MRI); 14 cases of the same group were also evaluated by transvaginal ultrasound. The degree of invasion evaluated by MRI and transvaginal sonography was compared to the pathological specimens. MRI was successful in evaluating myometrial invasion in 2.5 of 30 cases (accuracy 83%, sensitivity 87%, specificity 78%, positive predictive value 82%, negative predictive value 84%). Evaluation with transvaginal sonography was accurate in 11 of 14 cases (accuracy 78%, sensitivity 80% specificity 77%, positive predictive value 87%, negative predictive value 66%).
