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.
