Representative images of multiparametric magnetic resonance imaging (MRI) and Ki-67 (magnification, ×200). A low Ki-67 hepatocellular carcinoma (HCC) lesion (white arrow) showed complete capsule, smooth tumor margin and non-enhancing capsule in MRI (A−E) with Ki-67 labeling index of 3.56% (F). And a high Ki-67 HCC lesion (white arrow) showed incomplete capsule, non-smooth tumor margin and enhancing capsule in MRI (G−K) with Ki-67 labeling index of 49.37% (L). T2W, T2-weighted; PRE, pre-contrast; AP, arterial phase; PVP, portal venous phase; HBP, hepatobiliary phase.
