Abstract

Hepatocellular carcinogenesis in cirrhosis is a multistage process that includes large regenerative nodules, dysplastic nodules, and hepatocarcinoma. The aim of this study was to establish whether contrast-enhanced Doppler ultrasonography (US) is able to distinguish between early hepatocellular carcinoma (HCC) and small nonmalignant nodules in cirrhosis. Between January 1998 and December 1999, 500 cirrhotic patients with no previous history of HCC or evidence of hepatic focal lesions were enrolled and prospectively followed-up with US every 6 months until December 2000. Sixty-one patients developed focal lesions, 12 multifocal, and 49 monofocal. Biopsy of focal lesions, contrast-enhanced Doppler US, and spiral computed tomography (CT) were performed in 41 consecutive patients with small (
