Iohexol compared to urografin meglumine in cerebral angiography. A randomized, double blind cross-over study

In a double blind cross-over study the non ionic, water soluble contrast medium iohexol has been compared to Urografin Meglumine by angiography in common carotid artery and vertebral artery. More subjective adverse effects were generally seen with Urografin than with iohexol and statistically there were significantly less changes in heart rate after iohexol but no significant changes in the intra-arterial recorded blood pressure.
