Abstract
A randomized blind trial of Iopamidol and meglumine calcium metrizoate (Triosil 280, Isopaque Cerebral) for cerebral angiography was performed in 30 patients. The Iopamidol was better tolerated and caused significantly less discomfort in patients than metrizoate. There was no difference in the quality of the radiographs. A further 13 patients also received Iopamidol for cerebral angiography with similar results. No adverse effects were observed in any of the patients. Iopamidol apparently has significant advantages over currently available contrast media for cerebral angiography.
