"Arteriography" is the general name for contrast radiographic examination of any artery. In practice, private terms are often used: depending on the purpose and place of administration of the contrast medium, aortography, coronary angiography, carotid and vertebral arteriography, celiacography, mesentericography, etc. Are distinguished. To perform all these types of angiography, the end of the X-ray contrast catheter is inserted into the test vessel. After the injection of contrast medium, it fills the main trunk and large branches, then passes into branches of medium and small caliber. Further, the contrast substance accumulates in the capillaries, causing the intensity of the shadow of the organs supplied with the vessel under study to increase. Finally, the contrast agent appears in the venous outflow pathways.
When a contrast medium is inserted into the artery on angiograms, the regular phases of the blood flow are consistently reflected: arterial, capillary (parenchymal), and venous. This allows us to judge regional hemodynamics.
