Visualization of vascular structures using x-rays requires the use of a radiographic contrast medium in order to distinguish them from surrounding tissues, which aside from bones, absorb x-rays poorly. Iodinated radiographic contrast agents have been used for this purpose since the 1950s. Since then, just as digitalization and evolution of imaging equipment technology have made significant strides in improving image quality and reducing exposure to ionizing radiation, refinements in the design of and judicious use of iodinated contrast has improved patient safety and reduced adverse outcomes.
