Temporal changes in abdominal CT and MRI findings. (a) Single-phase contrast-enhanced CT; (d, i) hepatic artery phase; (e, j) portal phase; and (f, k) equilibrium phase in dynamic abdominal CT imaging. T2-weighted (b, g, l) and DWI (c, h, m) MRCP images. Absence of abnormalities in the intrahepatic bile ducts during initial examination. (a, b, c) Images showing dilatation of B8 (d, e, f, g) and a small area of high signal intensity observed on DWI (h). Preoperative imaging revealing a tumor with ring enhancement at the root of B8 (i, j, k, l), corresponding to that area, and the high-signal intensity on DWI imaging increasing in size (m)
