Evaluation of angiographically assisted spiral CT in surgical cases of hepatocellular carcinoma considering recurrent cases.
Between June 1993 and July 1996, computed tomography during arterial portgraphy (CTAP) was performed on 22 patients with hepatocellular carcinoma (HCC) and liver cirrhosis before surgery. In 17 out of 22 patients, CT hepatic arteriography (CTA) was combined with CTAP. All 22 patients underwent definitive surgery. In 16 patients in which CTA was successfully performed, 20 HCC nodules and 28 pseudolesions were detected. The pseudolesions were depicted larger in size with CTA than with CTAP, formed a variety of shapes, and were enhanced homogeneously, while HCC nodules were depicted larger with CTAP than with CTA, formed a round or wedge shape, and were sometimes enhanced heterogeneously. Recurrence was diagnosed in 9 of 22 patients. Five recurrent lesions in 4 patients were already revealed by pre-operative CTAP. CTA was performed in only 1 of 5 lesions. The diagnostic accuracy for HCC significantly improves by recognizing by recognizing pseudolesions with CTA and CTAP.
