[Experiences with the nonionic contrast medium iopamidol in cerebral angiography].

The rate of cerebral angiographies is bound to diminish in the present era of new imaging methods of low invasiveness. However, this examination method will continue to be an often decisive method to effect diagnostic visualisation of the cerebral vessels, so that the introduction of contrast media with low toxicity and good tolerance represents a great step forward, the more so since the risk of general anaesthesia can be often avoided. This fact, together with the substantial improvement in catheter technique, raises the method--provided it is conducted in special well-equipped departments--to a level of high diagnostic value, complications having become extremely rare if not completely eliminated.
