From: Correlation analysis of MR elastography and Ki-67 expression in intrahepatic cholangiocarcinoma
Intrahepatic cholangiocarcinoma of the high Ki-67 group in a 62-year-old man (arrows) showed (a) hyperintensity on diffusion-weighted image (b = 500 s/mm2), (b) hypointensity in the tumor periphery on apparent diffusion coefficient map (1.054 × 103 mm2/s). c The magnitude image and (d) stiffness map showed a high tumor stiffness value of 12.68 kPa. e Photomicrograph (Ki-67 immunostaining × 200) showed Ki-67 labeling index of 60%. A small satellite nodule can be seen beside the major lesion
