Effect of iohexol, metrizamide and ioxaglate on the blood-brain barrier
The effect upon the blood-brain barrier of the non-ionic contrast medium iohexol, compared with that of ioxaglate and metrizamide, was analysed. The contrast media were injected selectively into the internal carotid arteries of rabbits, and 197Hg Ac2 and Trypan blue were used as markers for evaluation of the injury. Less injury to the blood-brain barrier was caused by iohexol.
