Purpose: To assess the value of mangafodipir trisodium-enhanced MR imaging for characterization of hepatocellular lesions.
Materials And Methods: Magnetic resonance images of 41 patients with 48 histopathologically proven hepatocellular lesions (20 cases of focal nodular hyperplasia [FNH], 4 adenomas, 15 hepatocellular carcinomas [HCCs], 7 regenerative nodules, and 2 others) were retrospectively studied. Magnetic resonance imaging was performed on a 1.
Purpose: The objective of this study was to evaluate the accuracy and complication rate of CT fluoroscopy-guided percutaneous core biopsies of the pancreas in patients with a suspected pancreatic neoplasm.
Materials And Methods: Sixty-three CT-guided biopsies were performed in 57 consecutive patients over a period of 20 months. Forty-nine of the 57 patients had a malignant lesion (85.
Objective: The purpose of this study was to evaluate the diagnostic accuracy of ferumoxides-enhanced MR imaging for screening malignant hepatic lesions before orthotopic liver transplantation.
Materials And Methods: The study comprised 48 patients who underwent MR imaging within 6 months before transplantation. Imaging techniques included unenhanced and ferumoxides-enhanced T1-weighted gradient-echo and T2-weighted fast spin-echo sequences and ferumoxides-enhanced T2(*)-weighted gradient-echo sequences.

A 37-year-old woman presented with an 18 month history of recurrent severe abdominal pain, recurrent diarrhea since her second year of life, and mild peripheral edema. CT and more clearly MRI revealed signs of small bowel and mesenterial edema with partial tubular appearance, which correlated well with the histopathologic findings shown in duodenal biopsy. This is the first report of MR findings in congenital intestinal lymphangiectasia with correlation with other imaging modalities.

Materials And Methods: A multi-detector row spiral CT protocol for the diagnosis of pulmonary embolism was used that consisted of scanning the entire chest with 1-mm collimation within one breath hold. In 17 patients with central pulmonary embolism, the raw data were used to perform reconstructions with 1-mm, 2-mm, and 3-mm section thicknesses.
