Intra-arterial digital subtraction angiography of the carotid arteries. Special reference to contrast media

Neuroradiology. 1986;28(3):195-8. doi: 10.1007/BF00548191.


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.
