Tolerability and efficacy of Hexabrix in cerebral angiography

In a double-blind study of 62 patients, Hexabrix was compared with Conray 60% in cerebral angiography. Both agents were injected into the same patient, the patient serving as his own control, and volumes injected into a single vessel were identical. Considerably less pain was experienced with Hexabrix. Changes in pulse, respiration and blood pressure were not significantly different. The two contrast media provided images of comparable quality.
