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.
使用第二代Acta 200 FS设备对25例肝癌患者进行了28次计算机断层扫描检查。注射前，肿瘤通常密度较低，在许多情况下程度较小，且不均匀，边界不明确。该方法的灵敏度为96%。仅在11例病例中能够对肿瘤定位进行精确研究，64%的病例做出了明确诊断。该方法在评估局部扩展程度方面仅具有中等效果。与其他肝脏检查方法（闪烁扫描、超声检查、动脉造影）相比，计算机断层扫描并不比超声检查更具优势，超声检查应作为初步检查方法。
