Figure 1. CT (A-D) and MRI (E and F) appearance of a histologically proven hepatocellular carcinoma in a 69-year-old patient with metabolic dysfunction steatotic liver disease and without liver cirrhosis. The tumor is isoattenuating (A) to the liver on unenhanced CT image (A). It shows non-rim APHE during the late HAP (B - arrow) and non-peripheral washout during the PVP (C) and LVP (D). The lesion is heterogeneous and hypointense on unenhanced fat-saturated T1 gradient echo image (E). After gadoxetic acid injection, the lesion shows non-rim APHE during HAP (F - arrow), washout during PVP (G), and a hypointense appearance on the hepatobiliary phase (H - asterisk). Note the presence of an enhancing capsule (small arrows) best depicted on LVP on CT (D) and PVP on MRI (G). CT: Computed tomography; MRI: magnetic resonance imaging; APHE: arterial phase hyperenhancement; HAP: hepatic arterial phase; PVP: portal venous phase; LVP: late venous phase.
