A slight improvement in image quality occurred with the use of iohexol when compared with meglumine-Na diatrizoate. There is less swallowing with iohexol, which gives better image registration when looking at the extracranial carotid arteries. A single significant tachycardia occurred with the ionic medium, but not with iohexol. Overall discomfort and minor adverse reactions were less with iohexol than with diatrizoate.
