Angiography is a diagnostic procedure performed primarily when symptoms suggestive of a heart attack are present, or when signs of blockages, damage, or abnormalities are observed in blood vessels. Through this procedure, specialist doctors accurately determine the source of the problem and the extent of damage to the blood vessels. Angiography plays an important role in the diagnosis of the following diseases:

* Coronary artery disease
* Peripheral artery disease
* Atherosclerosis
* Blood clots
* Aneurysm
