Thirty-three patients with primary and secondary tumors of the liver were examined by computer-tomographic arteriography. Methods of selective intraarterial amplification of a computer-tomographic image is presented, as are indications for and contraindications against the use of such technique. The authors have united on a single working place a computer-aided tomographer Somatom DR-2 and a Siremobil device, this essentially simplifying the examinations. Selective administration of a contrast agent through a catheter into the celiac trunk helped significantly augment the density (200-240 U) of liver parenchyma, this permitting the detection of focal liver involvement undetectable by standard computer tomography because of a density similar to that of liver parenchyma. The method permitted the detection of foci 3-5 mm in diameter. On the whole use of computer-tomographic arteriography helped improve the diagnosis of focal liver involvement by 27%.
对33例原发性和继发性肝肿瘤患者进行了计算机断层血管造影检查。介绍了计算机断层图像选择性动脉内增强的方法,以及使用该技术的适应证和禁忌证。作者将计算机辅助断层扫描仪Somatom DR - 2和Siremobil设备整合在一个工作台上,这大大简化了检查过程。通过导管将造影剂选择性注入腹腔干,有助于显著提高肝实质的密度(200 - 240单位),这使得能够检测出由于密度与肝实质相似而在标准计算机断层扫描中无法检测到的肝脏局灶性病变。该方法能够检测出直径为3 - 5毫米的病灶。总体而言,计算机断层血管造影的使用有助于将肝脏局灶性病变的诊断准确率提高27%。
