[Cerebral and spinal angiography with metrizamide (amipaque) (author's transl)]

Metrizamide (Amipaque) has been used as the contrast medium for angiography in neuroradiological investigations. Solutions containing 280 mgI/ml. are well tolerated and produce good contrast. The most important difference from previously used contrast media is the lack of pain when injections are made selectively or super-selectively into the external carotid artery and its branches, or into the spinal arteries.
