Noninvasive imaging of hepatocellular carcinoma: From diagnosis to prognosis

Figure 2 Hepatocellular carcinoma in 47-year-old male with chronic hepatitis B. 4.7-cm-sized mass in right anterior hepatic section shows hypointensity on unenhanced T1-weighted image (A), hyperenhancement in arterial phase (B), hypointensity relative to the surrounding liver parenchyma in portal venous phase (C), and 20 min hepatobiliary phase (D). An enhancing capsule (white arrow, the peripheral rim of smooth enhancement) in portal venous phase, mosaic architecture, intermediate hyperintensity on T2-weighted images (E), and restricted diffusion (F) are also visible. The mass was confirmed as Edmonson-Steiner grade II at 200 × magnification with hematoxylin-eosin (HE) staining (D).
