OBJECTIVE Our objective was to determine the accuracy, precision, and reliability of MR imaging as a technique for measurement of the femoral antetorsional angle. SUBJECTS AND METHODS We used MR imaging to measure anteversion of the femoral neck in 44 patients: 19 children (range, 3-17 years old; mean, 11 years old) and 25 adults (range, 18-83 years old;(More)
OBJECTIVE Our purpose was to describe the morphologic appearance of musculoskeletal lesions in patients with cystic echinococcosis shown by CT and MR imaging. CONCLUSION Patients with musculoskeletal lesions of cystic echinococcosis typically have cystic structures in adjacent soft tissues. These cysts morphologically resemble abscesses, with peripheral(More)
Disparity in prognosis and management between primary and secondary pancreatic tumours makes recognition of metastases to the pancreas on CT and MRI an important goal. Three different patterns of secondary pancreatic tumours may be seen: localized, multifocal, or diffuse enlargement. CT findings include hypodense lesions, which show rim enhancement(More)
PURPOSE To ascertain whether the configuration and location of leakages identified at computed tomography (CT) could provide evidence of their angiographically and fluoroscopically confirmed causes. MATERIALS AND METHODS Fifty patients aged 26-79 years underwent endovascular repair of traumatic (n = 4) or arteriosclerotic (n = 46) aortic aneurysms (four(More)
PURPOSE This is a study of 140 patients undergoing MR mammography (MRM) for evaluation of possible local recurrent disease following breast-conserving surgical treatment of mammary carcinoma. MRI was performed 1-228 months (mean 28.3 months) postoperatively. METHOD MRM and interpretation of the dynamic measurements were performed in a standardized manner(More)
When the radiologist is faced with a well-circumscribed tumoral mass in the pancreas, knowing when to direct the patient toward nonsurgical biopsy instead of surgical biopsy and staging is critical. Lymphoma does not require surgical staging or a palliative Whipple's procedure before chemotherapy or radiation therapy. A better overall prognosis with(More)
PURPOSE The aim of this study was to investigate the effectiveness and complications of combined external beam and intraluminal high dose rate irradiation and various adjuvant biliary drainage techniques on patients with bile duct carcinomas. METHODS AND MATERIALS Eighteen patients with carcinomas of the hepatic duct bifurcation and 12 patients with(More)
OBJECTIVE The purpose of this study was to determine the diagnostic accuracy of sonography versus magnetic resonance imaging (MRI) and positron emission tomography (PET) in the characterization of adnexal masses. METHODS One hundred and one patients with asymptomatic adnexal masses, which were scheduled for laparoscopy, underwent preoperative transvaginal(More)
PURPOSE To evaluate patient acceptance of computed tomography (CT) colonography compared with conventional colonoscopy by means of a self-assessed questionnaire. MATERIAL AND METHODS Four-hundred-and-one patients with valid address information from our patient collective were preselected. Patient acceptance was evaluated retrospectively using a(More)
