AIM A dose ranging multicentre phase-II clinical trial was conducted to evaluate the efficacy of ultrasmall superparamagnetic iron oxide (USPIO) ferumoxtran-10 for magnetic resonance (MR) imaging of focal hepatic lesions. MATERIAL AND METHODS Ninety-nine patients with focal liver lesions received USPIO at a dose of 0.8 (n = 35), 1.1 (n = 32), or 1.7 (n =(More)
PURPOSE To describe the CT imaging findings of recurrent malignant peritoneal mesothelioma in patients who underwent debulking surgery. MATERIALS AND METHODS The history, clinical and laboratory data, and imaging studies of 13 patients with histologically proven diagnosis of Malignant Peritoneal Mesothelioma (MPM) and their recurrence following(More)
OBJECTIVE This study was conducted to assess the correlation with patient outcome and interobserver variability of a modified CT severity index in the evaluation of patients with acute pancreatitis compared with the currently accepted CT severity index. MATERIALS AND METHODS Of 266 consecutive patients diagnosed with acute pancreatitis during a 1-year(More)
The objective of this study is to assess the trends in imaging utilization in adults with diagnosis of appendicitis and the role that imaging plays in the escalating appendicitis hospital charges. Data on demographics, imaging utilization, and charges of all patients discharged after a diagnosis of appendicitis during 6 years (1999-2004) were obtained from(More)
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)
Bowel ischemia may be caused by many conditions and manifest with typical or atypical and specific or nonspecific clinical, laboratory, and radiologic findings. It may mimic various intestinal diseases and be confused with certain nonischemic conditions clinically and at computed tomography (CT). Bowel ischemia severity ranges from mild (generally transient(More)
This article discusses the most important benign liver tumors, both in adult and pediatric patients. A pathologic discussion of each neoplasm is included to provide a basis for understanding the radiologic-pathologic correlation that is used throughout the monograph. The benign liver tumors are presented according to their frequency. Therefore, hemangioma,(More)
We present magnetic resonance imaging findings in a patient with proven hepatic veno-occlusive disease (VOD) caused by the use of "poppers," a recreational drug used during anal intercourse. Although this report emphasizes the differential magnetic resonance imaging features between VOD and Budd-Chiari syndrome, our case is unique because the VOD was(More)
Magnetic resonance (MR) imaging is a powerful tool in the evaluation of primary liver neoplasms. Determination of tumor extent and tissue characterization is provided with standard spin-echo T1- and T2-weighted imaging and is enhanced by the application of advanced sequences such as gradient-echo, fast spin-echo, and fat suppression techniques.(More)
