Abstract
To show the normal contrast enhancement patterns of the upper abdominal organs, dynamic gadopentetate dimeglumine-enhanced MR imaging of the upper abdomen was performed in 48 patients. Although all patients were originally examined for focal hepatic lesions, none of them had diffuse parenchymal disease of any of the examined organs. Dynamic gadopentetate dimeglumine-enhanced MR imaging was done by using a heavily T1-weighted gradient-echo sequence (100/5 [TR/TE], 80 degrees flip angle) performed before, and repeatedly for a period of 10 min after, an IV bolus injection of gadopentetate dimeglumine (0.1 mmol/kg). Signal enhancement in each of the organs was calculated by measuring the signal intensity before and after administration of contrast medium. All organs showed signal enhancement within the first 2 min (p less than .001) and a continuous decline thereafter. The enhancement of the pancreas, liver, stomach wall, spleen, and renal cortex reached peaks of 75%, 78%, 96%, 144%, and 216%, respectively, 4...
