Direct microscopic observation of reactions of blood cells and peripheral blood vessels to various contrast materials revealed adverse responses in some cases. These included arterial and venous constriction, either local or general, crenation of red blood cells, adherence of white blood cells to vessel walls and clumping and adherence of platelets. Renovist caused none of the above mentioned reactions and no change in vessel diameters. Hypaque-M 90 per cent caused arterial and venous vessels to dilate and stopped venous vasomotion. The cellular elements were unaffected.

    Iomeprol is a nonionic, monomeric iodinated contrast medium. Unlike the older ionic agents, iomeprol has low chemotoxicity, osmolality and viscosity and high water solubility. Compared with other nonionic contrast media, the osmolality and viscosity are lower and the water solubility is reported...

    Vascular reactions after administration of all classes of iodinated x-ray contrast media are well known side effects of these drugs. Both vasodilation and vasoconstriction have been observed. The manner and extent of the change in vessel tone depends on the type of contrast medium, species,...
