OBJECTIVE To determine the relative accuracy of CT or MR imaging in the detection of inoperable tumor sites prior to cytoreductive surgery in a large series of patients with newly diagnosed primary epithelial ovarian cancer. METHODS One hundred thirty-seven women with newly diagnosed primary epithelial ovarian cancer underwent CT (n = 91) or MR imaging (n(More)
PURPOSE To determine if performing magnetic resonance (MR) spectroscopic imaging, compared with performing T2-weighted MR imaging alone, improves the detection of locally recurrent prostate cancer after definitive external beam radiation therapy. MATERIALS AND METHODS This retrospective single-institution study was approved by the committee on human(More)
This study was designed to assess the incidence, magnitude, and impact upon retrievability of vena caval perforation by Günther Tulip and Celect conical inferior vena cava (IVC) filters on computed tomographic (CT) imaging. Günther Tulip and Celect IVC filters placed between July 2007 and May 2009 were identified from medical records. Of 272 IVC filters(More)
BACKGROUND Gastric bypass (GBP) is the most common operation performed in the United States for morbid obesity. However, weight loss is poor in 10% to 15% of patients. We sought to determine the independent factors associated with poor weight loss after GBP. DESIGN Prospective cohort study. We examined demographic, operative, and follow-up data by means(More)
BACKGROUND Portomesenteric venous thrombosis (PVT) is an uncommon but potentially lethal condition reported after several laparoscopic procedures. Its presentation, treatment, and outcomes remain poorly understood, and possible etiologic factors include venous stasis from increased intra-abdominal pressure, intraoperative manipulation, or damage to the(More)
PURPOSE To determine whether magnetic resonance (MR) imaging and MR spectroscopic imaging findings can improve predictions made with the Kattan nomogram for radiation therapy. MATERIALS AND METHODS The institutional review board approved this retrospective HIPAA-compliant study. Ninety-nine men who underwent endorectal MR and MR spectroscopy before(More)
OBJECTIVE The purpose of this report is to describe the frequency and histopathologic basis of benign hypervascular liver nodules seen on CT in patients with autoimmune hepatitis. CONCLUSION Benign hypervascular liver nodules may be seen on CT in patients with cirrhosis due to autoimmune hepatitis and may represent large regenerative nodules. This(More)
OBJECTIVE To compare the diagnostic accuracies and interreader agreements of the Prostate Imaging Reporting and Data System (PI-RADS) v. 2 and University of California San Francisco (UCSF) multiparametric prostate MRI scale for diagnosing clinically significant prostate cancer. METHODS This institutional review board-approved retrospective study included(More)
PURPOSE To retrospectively determine the effect of liver iron deposition on the evaluation of liver fat by using opposed-phase magnetic resonance (MR) imaging. MATERIALS AND METHODS Committee on Human Research approval was obtained, and compliance with HIPAA regulations was observed. Patient consent was waived by the committee. Thirty-eight patients with(More)
PURPOSE To estimate the prevalence of underlying adenocarcinoma of the colon in patients in whom acute diverticulitis was diagnosed at computed tomography (CT) and to compare that to the prevalence of colon cancer in the general population. MATERIALS AND METHODS A comprehensive literature review was performed to find articles in which patients with CT(More)
