Intravascular iodinated contrast media are used in high doses and high concentrations to achieve the necessary x-ray attenuation. These solutions have densities, viscosities, and osmolalities considerably higher than body fluids. The properties of the solutions are responsible for many of the dose-dependent side effects of intravascular injection. There are significant differences among the media available today; however, all will produce some side effects.
血管内碘化造影剂以高剂量和高浓度使用，以实现必要的X射线衰减。这些溶液的密度、粘度和渗透压显著高于体液。这些溶液的特性是血管内注射许多剂量依赖性副作用的原因。如今可用的造影剂之间存在显著差异；然而，所有造影剂都会产生一些副作用。
