在CT扫描中为了显示某些病灶,需要注射造影剂进行强化扫描,其主要目的就是增加病变组织与正常组织的密度差别,从而提高病变的显示率与诊断的准确率。 1 资料与方法本人从事CT工作十年来,强化扫描病例绝大多数使用的都是离子型造影剂如复方泛影葡胺,安其格纳芬,少数使用非离子型造影如优维显、欧乃派克。其中使用离子型造影剂增强扫描3500多例,使用非离子型造影剂增强扫描400多例,均采用快速 In the CT scan in order to show some lesions, need to inject contrast media for intensive scanning, the main purpose is to increase the density of diseased tissue and normal tissue differences, thereby increasing the rate of display lesions and diagnostic accuracy. 1 Materials and Methods I work in CT for more than 10 years, the vast majority of enhanced scan cases are using ionic contrast agents such as compound diatrizoate meglumine, and its agarfin, a small number of non-ionizing radiography such as excellent Victoria significant, Europe It is Parker. Among them, more than 3,500 cases were scans enhanced with ionic contrast agents and more than 400 cases were enhanced with nonionic contrast medium,
