Imaging plays a mainstay role in evaluation of patients with bladder cancer, especially for diagnosis, local and distant staging and treatment follow up. In this article, we aim to review and to update conventional and functional imaging methods used in clinical management of bladder cancer. 相似文献

The aim of this study is to investigate the efficacy and long-term results of percutaneous transcatheter ethanol sclerotherapy
(PTES) for postoperative pelvic lymphocele treatment. Fifty-two patients who were referred for lymphocele treatment were included
in this study. Sixty lymphoceles of 52 patients were treated by percutaneous treatment with or without ethanol sclerotherapy.
Lymphoceles developed in 47 and 5 patients, who underwent gynecologic malignancy operation (31 ovarian cancer, 6 cervix cancer,
10 endometrial cancer) and renal transplantation, respectively. Lymphoceles were catheterized by ultrasonography and fluoroscopy
guidance using the Seldinger technique. Lymphoceles smaller than 150 mL underwent single-session ethanol sclerotherapy and
the others were treated by multiple-session ethanol scleortherapy. In 10 patients, percutaneous ethanol sclerotherapy could
not be performed and they were treated only by percutaneous catheter drainage. The mean lymphocele volume was 329 mL (15–2900
mL). The mean catheterization duration was 11.8 days (1–60 days). The mean follow up time was 25.8 months (2–64 months). The
initial treatment was successful in 46 out of 50 (91%) lymphoceles treated with PTES and 7 out of 10 (70%) lymphoceles treated
with percutaneous catheter drainage. Minor complications (secondary infection and catheter dislodgement) were noted in seven
(11.6%) patients. Recurrence developed in four and three patients who were treated by PTES and percutaneous catheter drainage,
respectively. Five of these patients were treated with PTES without further recurrence. Percutaneous transcatheter ethanol
sclerotherapy is an effective and reliable method for the treatment of postoperative lymphoceles. 相似文献

Purpose
The major purpose of this paper is to outline and correlate US, CT and MR imaging findings of liver in patients with Wilson's disease.Materials and methods
Twenty-eight patients (10 male, 18 female, median age 16) with Wilson's disease were examined with US, CT and MRI. Liver echogenicity, echo pattern, contour irregularity, periportal thickness, perihepatic fat layer thickness, the presence of focal parenchymal lesion, and other associated findings were recorded by US in every patient. CT and MRI were done in 20 and 12 patients, respectively.Results
Contour irregularity was observed in 24 patients and heterogeneous parenchymal echo pattern was seen in 26 patients with US. The presence of increased perihepatic fat layer was observed in eight patients. Severe parenchymal atrophy was seen in all lobes of the liver including caudate in contrast to post-viral chronic liver disease. Nineteen patients had periportal thickening. US showed multiple hyper and/or hypoechoic nodules smaller than 1 cm in 13 patients. MRI demonstrated small nodular hypointense areas on T2-weighted images in five patients. In only one patient these nodules showed contrast enhancement in CT and MR and pathologically proved to be dysplastic nodule.Conclusion
Wilson's disease involving the liver has several unique radiological findings in comparison to other types of cirrhosis. These specific features include multiple nodular lesions in the liver, presence of perihepatic fat layer and normal caudate lobe which is contrary to other types cirrhosis. Liver injury in the Wilson's disease can be defined by imaging modalities, especially by US which we think is the most precise imaging modality to detect early parenchymal changes in the progress of the disease. 相似文献46.

Purpose
To evaluate the treatment of simple endometrial hyperplasia without atypia with different gestagens.Methods
Sixty premenopausal women with histologically documented endometrial hyperplasia without atypia were included in this prospective controlled study. Patients were randomized into two groups: Group I included 30 patients who received lynestrenol (LYN) in a dose of 15 mg/d, while Group II included 30 patients who received micronized progesterone (MP) 200 mg/d for 12 days per cycle for 3 months. Patients were reevaluated with endometrial curettage after treatment. MP and LYN regimens were compared to regression, resolution or persistence rates and metabolic parameters.Results
After 3 months of treatment in both groups, none of the cases progressed. In LYN group, the rate of resolution was observed to be higher compared to MP group (p = 0.045). LYN was found more effective inducing resolution in patients more than 45 years compared to MP (p = 0.036). When we compare both groups after 3 months of treatment, there was no statistically significant difference in BMI, total cholesterol, HDL, LDL and fibrinogen level between two groups. The rate of patients without any side effects was found to be similar in both groups (p = 0.5).Conclusion
LYN which is a synthetic progestin ensures better endometrial control compared to MP in simple hyperplasia without atypia in the patients of premenopausal age especially in ages more than 45 years. 相似文献48.

To assess the impact of scanning direction on the image quality of coronary artery bypass grafts (CABGs), native coronary
arteries (NCAs) were examined by electrocardiographically (ECG) gated 16-row multidetector computed tomography (16-MDCT).
Eighty-two patients with 209 grafts were studied by 16-MDCT. Forty-one patients with 111 grafts were scanned craniocaudally.
Forty-one patients with 98 grafts were scanned caudocranially. CABG, native coronary arteries were examined in four (proximal,
middle, distal, distal anastomoses), three (proximal, middle, distal) segments, respectively. Subjective image quality on
a four-point scale was calculated for segments. Scores of groups were compared. Results Image quality scores of proximal,
distal segments of the right coronary artery (RCA) were better in caudocranially scanned group (P<0.05). When we subgrouped patients according to initial heart rates (IHR) (group 1, <65 beats/min; group 2, ≥65 beats/min),
there was no statistical significance between image quality scores of coronary arteries, CABG when IHR was <65 beats/min in
groups regardless of scanning direction. Scores of anastomotic segment of CABG to RCA, middle segments of circumflex coronary
artery, proximal and distal segments of RCA in caudocranially scanned group were better when the IHR is ≥65 beats/min compared
with the craniocaudally scanned group. When the IHR of the patient is ≥65 beats/min, performing ECG-gated 16-MDCT angiography
in the caudocranial direction provides better image quality for evaluation of coronary arteries and CABGs. 相似文献
