title: Clinical usefulness of computed tomography arteriography and computed tomography during arterial portography for the diagnosis of early and early advanced hepatocellular carcinoma.
abstract: 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.
  
  
  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 approximately 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.
  
  
  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.
  
  
  CONCLUSIONS
  A combination of CTA and CTAP is useful for the diagnosis of early HCC and early advanced HCC.
