Cerebral computed tomography was performed in 60 patients referred for pre- and postcontrast scanning. The patients were randomly sampled with a nonionic contrast medium, iohexol, and an ionic contrast medium, sodium metrizoate. No complications were seen, and the adverse effects, usually a feeling of warmth, were very minor with both contrast media, but iohexol caused less discomfort than sodium metrizoate. A series of measurements of the attenuation values of well defined intracranial structures was performed and no difference in enhancement was found between the two contrast media.
对60例接受造影前和造影后扫描的患者进行了脑部计算机断层扫描。患者被随机分为两组，分别使用非离子型造影剂碘海醇和离子型造影剂甲泛葡胺钠。未观察到并发症，两种造影剂的不良反应通常为温热感，均非常轻微，但碘海醇引起的不适比甲泛葡胺钠少。对明确的颅内结构的衰减值进行了一系列测量，发现两种造影剂之间的增强效果没有差异。
