A cross-over test in intra-arterial digital subtraction angiography (IADSA) of the carotid arteries was performed in 50 patients to evaluate image quality and side-effects with iohexol and metrizoate injected at concentrations of 100 mg I/ml by hand. The image quality was excellent or good in all cases. Although the severity and the frequency of side-effects were higher with metrizoate, both contrast media were suitable for IADSA at this low concentration. No complications were seen. It was assumed that the risk with IADSA was less than that of conventional precerebral angiography when performed semi-selectively and with small amounts of contrast media, as in this study.
对50例患者进行了颈动脉动脉内数字减影血管造影（IADSA）的交叉试验，以评估手动注射浓度为100 mg I/ml的碘海醇和甲泛葡胺时的图像质量和副作用。所有病例的图像质量均为优或良。虽然甲泛葡胺的副作用严重程度和发生率更高，但两种造影剂在这种低浓度下都适用于IADSA。未观察到并发症。据推测，如本研究中那样进行半选择性且使用少量造影剂时，IADSA的风险低于传统脑前血管造影。
