We investigated the feasibility of using and the resultant image quality of zoomed diffusion-weighted echo-planar imaging (z-EPI) for hilar cholangiocarcinoma assessments. Compared with conventional single-shot EPI (c-EPI), z-EPI showed better delineation of anatomic structures in the hepatic hilar region, better lesion conspicuity, and overall higher image quality. Bile duct wall lesion delineations and lumens were also improved in z-EPI in four of 16 patients. These findings suggest that z-EPI may be preferred for improved imaging of hilar cholangiocarcinoma.
