Nineteen patients with clinically proven hepatocellular carcinoma were studied by dynamic computed tomographic (CT) scanning. Ten consecutive 3 sec scans were performed within 30 sec, providing uninterrupted data collection. Dynamic CT scanning was useful in recognizing tumor vascularity, multiple small tumors, isodense tumors on conventional CT scans, the capsule of an encapsulated hepatocellular carcinoma, arteriovenous shunts, and vascular pools. Time-density curves were useful in evaluating the hemodynamics of the tumors; these could be classified into three types according to differences in their enhancement patterns.
