Angiography or arteriography is referred to process of medical imaging technique used to visualize the interior organs of the body. Particular interest is given to the arteries, veins and the heart chambers during any angiography.

The process of angiography can be divided into many types like xray study blood vessels, cerebral angiography, coronary angiography, pulmonary angiography, kidney angiography as per the patients' requirement.

Coronary angiography is one of most common angiography. It is performed to visualize the blood in the coronary arteries. In this type of angiography a long, thin, flexible tube called a catheter is used to administer the x-ray contrast agent at the desired area. It is then threaded into an artery in the groin or forearm. The tip is then advanced through the arterial system into one of our bodies' two major coronary arteries.

An expert on the procedure of angiography can visualize x-ray images of the transient radiocontrast distribution within the blood. He /she can thus determine the size of the artery openings.

Cerebral angiography is usually used to detect most vascular abnormalities of the brain like arteriovenous malformations and aneurysms. Some doctors also perform cerebral angiography is required to confirm brain death.

Similarly, pulmonary angiography refers to an x-ray study of blood vessels that is supplied to the lungs. It is generally used to find a blood clot) in these blood vessels.

Kidney angiography also known as renal angiography, on the other hand refers to a process where an expert look at the arteries that supply blood to the kidneys. Kidney angiography is usually done to evaluate blood flow to the kidneys, detect any blockages/narrowing in the kidney arteries, determine the severity of the blockage for proper diagnosis, identify a possible cause for high blood pressure and last but not the least, identify a possible cause for poor kidney function.
