How can cardiac catheterization help in the diagnosis of atherosclerosis?

ANSWER

During this procedure, your doctor inserts a small flexible tube into an artery and guides it up to the coronary arteries. The doctor injects dye through the tube and watches as it flows inside those arteries. This allows the doctor the chance to directly locate and measure any blockages in the coronary arteries. During a cardiac catheterization, a cardiologist may also be able to open up any clogged arteries with a procedure called an angioplasty.
