Aortography Health Dictionary

Aortography: From 3 Different Sources


An imaging technique that enables the aorta (the main artery of the body) and its branches to be seen clearly on X-ray film following injection of a contrast medium (a substance that is opaque to X-rays).

Aortography is used if surgery is needed to treat an aneurysm (ballooning of the aorta).

Aortography is the technique of rendering the AORTA visible in an X-ray ?lm by injecting a radio-opaque substance into it. The procedure is used to detect the presence of an ANEURYSM. (See also ANGIOGRAPHY.)

n. imaging of the aorta. In the traditional method a series of X-ray images were taken during the injection of X-ray dye into the aorta via a catheter. This technique has been largely replaced as a primary investigation by other *cross-sectional imaging methods, such as CT aortography and MR aortography.

Angiography

An imaging procedure that enables blood vessels to be seen clearly on X-ray film following the injection of a contrast medium (a substance

that is opaque to X-rays). Angiography is used to detect conditions that alter the appearance of blood vessels, such as aneurysm, and narrowing or blockage of blood vessels by atherosclerosis, or by a thrombus or embolus. It is also used to detect changes in the pattern of blood vessels that supply organs injured or affected by a tumour.

Carotid angiography (of the arteries in the neck) may be used to investigate transient ischaemic attacks. Cerebral angiography can be used to detect an aneurysm in the brain or pinpoint the position of a brain tumour. Coronary angiography, often combined with cardiac catheterization, can identify the sites of narrowing or blockage in coronary artery disease. Digital subtraction angiography uses computer techniques to process images and remove unwanted background information.

Angiographic techniques have been adapted to allow certain treatments that, in some cases, eliminate the need for surgery (see angioplasty, balloon; embolization). (See also aortography.)... angiography
