1) Objective: We examined the clinical usefulness of two techniques of Angio Computed tomography (CT) , namely, CT arteriography (CTA) and CT during arterial portography (CTAP) , for the diagnosis of early hepatocellular carcinoma (HCC) and early advanced HCC.
2) Materials and Methods: The subjects were six patients with a total of seven lesions: three had one early HCC lesion each, and three had four early advanced HCC lesions between them. There were five men and one woman, aged 61~73 years (mean: 65 years) . A catheter was inserted into each inguinal artery according to Seldinger's method, and the results of CTA and CTAP were compared with those of conventional CT.
3) Results: Visualization of tumor borders, arterial blood feeding areas, and portal blood flow areas gave results equal to or better than those of conventional CT.
4) Conclusions: A combination of CTA and CTAP is useful for the diagnosis of early HCC and early advanced HCC.
