Detection of hypervascular hepatocellular carcinoma: Comparison of multi-detector CT with digital subtraction angiography and Lipiodol CT

Figure 1 Diagram of nodule detectability by each imaging technique.

Figure 2 A hepatocellular carcinoma nodule identified by Lipiodol CT but not by biphasic MDCT in a 53-year-old man. A: MDCT scan during the arterial phase shows a 3-cm hypervascular tumor in S5 (arrowhead); B: DSA confirms the MDCT findings (arrowhead); C: Lipiodol CT identifies another tumor in S6 (arrowhead) in addition to S5.
