Fig. 2D —Hepatocellular carcinoma (HCC) in 73-year-old woman.
Corresponding transverse C-arm CT images after transarterial contrast media
administration in arterial (C) and portal venous (D) phases.
Although tumor shows comparable enhancement pattern to MDCT in arterial phase
(C), portal venous phase (D) shows large perfusion defect. On
C-arm CT, additional nodular lesion was detected in liver segment II
(white arrow, C and D); it was rated HCC by both
readers. In this case, scan coverage was incomplete because of liver
extension.
