Evaluation of a 10-minute comprehensive MR imaging examination of the upper abdomen.

abstract：:The abdominal computed tomographic (CT) scans from 61 patients with biopsy-proved Helicobacter (formerly Campylobacter) pylori gastritis were retrospectively reviewed. The CT scans were interpreted on the basis of the original report of the findings at CT examination and without knowledge of the results of biopsy. Of ...
