Arteriography

"Arteriography" is a general name for a contrast X-ray examination of any artery. In practice, specific terms are often used: depending on the purpose and place of administration of the contrast agent, a distinction is made between aortography, coronary angiography, carotid and vertebral arteriography, celiacography, mesentericography, etc. To perform all these types of angiography, the end of the X-ray contrast catheter is inserted into the vessel being examined. After the contrast agent is injected, it fills the main trunk and large branches, then passes into the medium and small caliber branches. Then the contrast agent accumulates in the capillaries, which increases the intensity of the shadow of the organs supplied by the vessel being examined. Finally, the contrast agent appears in the venous outflow tracts.

When a contrast agent is injected into an artery, the angiograms normally consistently reflect the regular phases of blood flow: arterial, capillary (parenchymatous), venous. This allows us to judge regional hemodynamics.
