From: Added value of CE-CT radiomics to predict high Ki-67 expression in hepatocellular carcinoma
Representative images of multiphase contrast enhanced CT (CE-CT). A-E high Ki-67 HCC lession (black arrow), A, non-rim APHE and internal arteries (white arrow) on AP, B-C, hypodense halo and PVTT on PP, wash out and enhancing capsule on DP; consisting of “internal arteries” and “hypodense halos” defined as TTPVI, E, High and low Ki67 expression (70.5%), the brown regions represent positive Ki67 expression; And F-J show low Ki-67 expression HCC lesion (black arrow), F, no internal arteries on AP, G-I, no hypodense halos and PVTT on PP, non-enhancing capsule on DP, no TTPVI present. J, low Ki67 expression (8.2%); AP, arterial phase; PP, portal venous phase; DP, delayed phase; PVTT, portal vein tumor thrombus; TTPVI, two-trait predictor of venous invasion
