CHOLANGIOCARCINOMA, PATHOLOGY, TUMORS
A study investigator (ABJ) correlated the recorded observations on EOB-MRI and CECT with those on explant pathology reports based on lesion size and segment location. Lesions were matched if the difference between the pathologically and radiologically measured sizes was less than 10 mm, and no similar-sized lesion was observed in the same segment. Cholangiocarcinoma and mixed HCC-cholangiocarcinoma tumors were analyzed as non-HCC tumors. HCCs detected only on histopathology without corresponding LR-4 or 5 imaging observations in the same segment location were regarded as false-negative (FN), and the contrary was defined as false-positive (FP).
