Histologically proven hepatocellular carcinoma (HCC) in a male patient with hepatitis B virus–related liver cirrhosis. Axial images of 1.5-T enhanced MRI (a–g) showed a lesion (arrows) in segment VI and segment VII junctional zone of the liver with a diameter of 3.2 cm, showing T1-weighted hypointensity (a), and without certain APHE in arterial phase (AP) (b), in portal venous phase (PVP) (c) showing hypointensity, the signals in out-phase reduced than that in in-phase (d-e), both T2WI (f) and DWI (g) showed hyperintensity. Based on major HCC features, this nodule would be assigned as LR-4 because of the lack of APHE. However, based on AF-LR, it can be upgraded
