[Computed tomography investigation of hepatic carcinomas (author's transl)]

Computed tomography examinations, using a second generation Acta 200 FS apparatus, were conducted on 28 occasions in 25 patients with hepatic carcinoma. Before injection, the tumor is usually of low density, to a small degree in many cases, and is heterogeneous and has indefinite limits. The sensitivity of the method is 96 p. cent. A precise study of the localization of the tumor was possible in only 11 cases, and a definite diagnosis was made in 64 p. cent. The method was only moderately effective in assessing the degree of regional extension. When compared with other methods for the investigation of the liver (scintigraphy, ultrasonography, arteriography), computed tomography shows no superiority over ultrasonography which should be employed for the initial examination.
