<P> CT angiography can act as a less invasive alternative to Catheter angiography . Instead of a catheter being inserted into a vein or artery , CT angiography involves only the injection of a CT - visible dye into the arm or hand via an IV line . CT angiography lowers the risk of arterial perforation and catheter site infection . It provides 3D images that can be studied on computer , and also allows measurement of heart ventricle size . Infarct area and arterial calcium can also be observed ( however those require a somewhat higher radiation exposure ) . That said , one advantage retained by Catheter angiography is the ability of the physician to perform procedure such as balloon angioplasty or insertion of a stent to improve blood flow to the artery . </P>
