Blood vessels cannot be seen on X-ray film unless they have been injected with a radiographic contrast medium. When an angiogram is used to examine arteries, it is known as an arteriogram. In studies of the arteries, the contrast medium is most commonly injected through a catheter inserted into an accessible artery (such as one in an arm or a leg) and then threaded into the artery to be studied. For example, in a coronary angiogram, a catheter may be inserted into the femoral artery of the leg and threaded upward into the coronary artery. When an angiogram is used to examine the veins, it is called a venogram. Venograms generally involve the veins deep in the lower legs.The visualization of blood vessels through radiological techniques.X-ray examination of blood vessels. A dye that is opaque to X-rays is injected into the artery and a rapid series of X-ray films is taken.Radiography of blood vessels made visible by injecting into them a radio-opaque substance. In the case of arteries this is known as arteriography; the corresponding term for veins being venography or phlebography. This procedure demonstrates whether there is any narrowing or ballooning of the lumen of the vessel \u2014 changes usually caused by disease or injury.A description of blood vessels and lymphatics.Various techniques used to examine the condition of blood vessels, typically involving a combination of radiological imaging and the administration of chemical tracers and contrast agents.A diagnostic technique called X-ray angiography employs the injection of a contrast medium, a substance that is visible on X-ray film, to achieve clear visualization of blood vessels. Digital subtraction angiography utilizes computer processing to enhance images and eliminate extraneous background details. Another method, magnetic resonance angiography (MRA), is capable of producing images of blood vessels without the need for a contrast medium.Angiography serves the purpose of identifying ailments that modify the visual presentation of blood vessels. These conditions encompass the presence of an aneurysm, characterized by the enlargement of an artery, as well as the constriction or obstruction of blood vessels due to the accumulation of fatty deposits along the arterial walls, known as atherosclerosis. Furthermore, it aids in the detection of abnormalities such as a thrombus, an irregular blood clot, or an embolus, a fragment of a clot transported through the bloodstream. Another application of angiography involves identifying alterations in the vascular network that supplies blood to organs afflicted or impacted by the presence of a tumor.The utilization of carotid angiography, which focuses on examining the arteries located in the neck, becomes valuable in the investigation of transient ischaemic attacks\u2014transient stroke symptoms that endure for a duration of fewer than 24 hours. Cerebral angiography presents another application, enabling the detection of brain aneurysms or the precise localization of brain tumors. In the realm of coronary artery disease, coronary angiography, often performed in conjunction with cardiac catheterization, proves instrumental in identifying areas of constriction or complete blockage within the coronary arteries.Within the realm of angiography, certain therapeutic interventions, such as balloon angioplasty and embolization, may be executed, occasionally obviating the necessity for surgical procedures that were previously deemed indispensable."}
