Summary

Selective left vertebral angiography was carried out in 25 rabbits comparing the toxic effects of iohexol and metrizamide (Amipaque). The iodine concentration for iohexol was 280 and 350 mg/ml and for metrizamide 350 mg/ml. Short general convulsions were seen in many of the animals with iohexol in the concentration of 350 mg iodine/ml. Cardiovascular reactions were seen with both contrast media, but were more marked with iohexol than with metrizamide in the concentration of 350 mg iodine/ml. Both iohexol and metrizamide are far less toxic than the ionic contrast medium metrizoate, but metrizamide seems to be less toxic than iohexol in vertebral angiography.
