Abstract:
Objective To determine the usefulness of MR diffusion-weighted imaging(DWI) in evaluating obstructive jaundice.Methods 25 patients with obstructed dilating bile ducts but without other basic hepatic diseases and 11 normal controls were studied byusing DWI.25 patients were divided into two groups(14 patients with jaundice and 11 patients without jaundice) depending on the serumlevels of total bilirubin.ADCs of liver were measured at workstation,and the mean ADCs were compared among the groups of patients and controlsusing one-way ANOVA.Results When b=500 s/mm~2,the mean ADCs of liver in three groups were significantly different(F=25.29,P0.05) between the ADCs in patients without jaundice and in controls.When b=300 s/mm~2,the mean ADCs of liver in three groups were significantly different(F=12.22,P
