Angiography is a test that uses an injection of a liquid dye to make the arteries easily visible on�X Rays. An angiogram is used to check the condition of blood vessels.�In Cardiac Angiography, a long wire called catheter is inserted into the artery in a suitable location�like the groin, or occasionally the arm�and is then pushed against the blood flow towards the heart. The doctor is able to view this on the fluoroscopy monitor and is guided till the tip reaches the heart area and subsequently manipulating it to the coronary artery.�When the catheter is in the correct position, the wire is pulled out and a�radioactive�dye is inserted through the catheter and�fluoroscopy photographs are taken.�The catheter is redirected to another coronary tube and the same photos are taken.�
