Forty patients with bladder carcinoma were examined preoperatively by means of magnetic resonance (MR) imaging. In all patients, total cystectomy with enterocystoplasty and pelvic node dissection was performed. The surgical and pathologic findings were correlated with the MR findings. Extension through the deep muscle of the bladder wall was present in 20(More)
Review of the literature shows no report of hibernoma of the thigh extending into the pelvis. Herein we report a case of hibernoma which appeared on CT and MR as a well-defined pelvic mass with contrast enhancement extending through the obturator foramen into the thigh. Fat was demonstrated by CT, whereas MR, using multiplanar sections, better analyzes the(More)
To evaluate the accuracy of abdominal radiography (AXR) for the detection of residual cocaine packets by comparison with computed tomography (CT). Over a 1-year period unenhanced CT was systematically performed in addition to AXR for pre-discharge evaluation of cocaine body packers. AXR and CT were interpreted independently by two radiologists blinded to(More)
OBJECTIVE To correlate CT and MR patterns of ovarian mature cystic teratomas (MCT). SUBJECTS AND METHODS CT and MR findings in 25 histologically proven ovarian MCT were retrospectively reviewed. MCT characterization at CT and MR was based on detection of fat and/or a Rokitansky protuberance. MR signal intensity and CT density numbers of fat were(More)
Metastatic peritoneal implants were assessed preoperatively with computed tomography (CT) in 38 patients with ovarian tumors. In the 106 biopsy specimens of gross peritoneal implants and the 118 random biopsy specimens obtained from these patients, metastatic deposits were detected in 27 of 38 (71%) patients and in 104 biopsy sites. CT depicted metastatic(More)
Nineteen patients with middle and lower rectal carcinomas were operated on, with abdominoperineal resection in 10 patients, lower anterior resection with coloanal anastomosis in 6 patients, and colorectal anastomosis in 3 patients. The distance of the lower margin of the tumor to insertion of the levator ani on the rectal wall was correctly evaluated by(More)
Correlation of imaging and anatomic findings in seven men with abdominal aortic graft prostheses (four "end-to-end" anastomoses and three "end-to-side" anastomoses) was done to compare the value of different imaging modalities in detecting postoperative complications, especially aortic anastomotic pseudoaneurysms (AAPs). In all cases, angiographic and CT(More)
OBJECTIVE The aim of this study is to analyze the ability of MR fat suppression techniques to characterize fat components of ovarian mature cystic teratomas (MCT) shown by CT. SUBJECTS AND METHODS MR images of eight MCTs of the ovary were obtained using standard sequences followed by a SPIR (spectral presaturation with inversion recovery) sequence in six(More)
OBJECTIVE Our goal was to determine the CT and US aspects of the fallopian tube in adnexal torsion. MATERIALS AND METHODS The CT scans and US studies of 10 patients with surgically proven unilateral torsion of the adnexa were reviewed. RESULTS On CT the fallopian tube on the involved side was identified in eight cases as an almost tubular or(More)
OBJECTIVE Exocrine function has been described in patients with diabetes. We hypothetized that patients with exocrine dysfunction have pancreatic atrophy. METHODS This is a cohort study of hospitalized patients. Thirty-five patients were selected after detection of impaired exocrine function in routine tests, and 17 patients were matched for age and body(More)
