Three types of enhancement morphology depicted in HCC patients. A: Type A. Marked and homogeneous enhance-ment of the entire HCC lesion in the posterosuperior segment of right hepatic lobe (black arrow). B: Type B. Bright periph-eral ring-like enhancement of HCC lesion on arterial phase image in the right posterosuperior segment (black arrow), and the dilated right hepatic artery (black arrow). C: Portal venous image at the same slice level as in (B). HCC lesion remained hypodense despite obvious enhancement of normal liver pa-renchyma elsewhere. D: Type C. Inhomogeneous patchy en-hancement of HCC lesion in right lower hepatic lobe from ar-terial phase image. Bright dots and linear shadows represent enhanced tumor vessels within the lesion.
