title: The optimal concentration of contrast medium for aortography and femoral arteriography: a comparison of Hexabrix 320 and Hexabrix 250.
abstract: A prospective double-blind randomised clinical trial of aortography and iliofemoral arteriography in 89 patients demonstrates that there is no difference in the diagnostic quality of the studies when Hexabrix 250 replaces Hexabrix 320. There is a minor reduction in patient subjective reaction, and the lower viscosity permits the use of smaller bore catheters. The major gain is that the cost of the contrast medium should be reduced by 22%.
