Iohexol in cerebral angiography. Survey and present state.

The non-ionic contrast medium iohexol has in 15 trials been extensively studied with regard to its use in cerebral angiography. In comparison with mainly the ionic contrast media there was a tendency for iohexol to less frequently cause subjective sensations of warmth and pain. There was a marked difference in the intensity of these sensations, those after iohexol injection being definitely less severe. No severe reactions, whatsoever, could be related to the new contrast medium, and it can be concluded that iohexol with great advantage can be used for cerebral angiography.
