The brain vasculature was explored by carotid arteriography in a total of 40 patients. Of these, 20 were examined with a nonionic contrast medium (Iopamidol 300), and the other 20 were examined with an established product (Uromiro 300). The study, conducted in double-blind fashion, showed that while the two products compared closely in terms of opacifying power, the nonionic compound, Iopamidol, was more readily tolerated subjectively and hence was conducive to better patient cooperation during angiography. This improved tolerability of the nonionic agent is attributed to the lower osmolarity of its solution compared to the conventional salified (ionic) product.
