Hepatocellular carcinoma (HCC) is the most frequent primary malignant liver tumor. Although its incidency in our population is relatively low, the improvement of differential diagnosis is important in patients with liver cirrhosis and active hepatitis B and C. Biphasic helical computed tomography has strong influence in treatment strategy, especially in evaluation of possibility of surgical resection. Multi-detector-row CT improve the advantages of biphasic helical CT, especially by the unique spatial resolution in any plane direction. Three-dimensional CT angiograms help to asses not only the hepatic vascular anatomy, but also the pathologic vascularisation of HCC. Authors report a group of 14 patients withHCCdiagnosed by helical CT; 4 of these patients underwentMDCT using sixteen-detector-row equipment.
