MR scans in a patient with chronic hepatitis, HCV related, and HCC and dysplastic nodule in liver segment V. a-b T2- and T1-weighted fast images show a heterogeneous nodule in liver segment V (arrow). The lesion shows the typical pattern of HCC with enhancement during the arterial phase c) and a wash-out sign on late dynamic phase d). On the late dynamic phase, a lesion near the “hilum-hepatis” is also detectable with loss of signal intensity to the surrounding liver parenchyma (open arrow). e On the fat-suppressed T1 -weighted 3D GRE image obtained during the hepatobiliary phase at 20 min after contrast injection, both lesions are hypointense to the surrounding liver parenchyma. f Histological analysis shows a hepatocellular carcinoma (upper image) and dysplastic nodule (lower image)
