Angiography is term for a range of X-ray tests used to detect and diagnose diseases of the blood vessels, such as weakening of the vessel walls, the narrowing or blocking of vessels, and to examine the chambers of the heart. A very small tube (catheter) is inserted into a blood vessel in your groin or arm. The tip of the tube is positioned either in the heart or at the beginning of the arteries supplying the heart, and a special fluid (called a contrast medium or dye) is injected. The X-ray is taken after the vessels have been injected with a substance (dye) that allows them to be seen on film. The pictures that are obtained are called angiograms.

• Coronary Angiography
  Coronary angiography is an X-ray examination of the blood vessels or chambers of the heart.
• Peripheral Angiography
  An angiography procedure to detect fatty deposits in the inner linings of the artery walls is called a Peripheral Angiography.
• Carotid Angiography
  This X-ray procedure detects the presence of fatty deposits in the Carotid Artery which carries blood to the brain.
