Purpose: To evaluate gadoxetic acid-enhanced MR imaging
with an emphasis on the usefulness of hepatobiliary
phase (HBP) in T-staging of gallbladder carcinoma.
Methods: 66 patients with confirmed gallbladder
carcinoma underwent gadoxetic acid-enhanced MR imaging.
Two radiologists independently reviewed two sets of MR
imaging without / with HBP for local tumor spread.
Results: This study yielded acceptable diagnostic
performance with gadoxetic acid-enhanced MR imaging with
the overall accuracies of 86.4% and 87.9% for each
observer. By adding HBP, the sensitivities to
differentiate T2 versus T3 lesions were increased
for both observers although there was no significant
difference (P > 0.05). Conclusions: Gadoxetic
acid-enhanced MR imaging provided acceptable diagnostic
performance for T-staging of gallbladder carcinoma.
Addition of HBP aids in detection of liver invasion.
