Radiation & Me


In cardiology, the most common x-ray exam is the angiogram. During an angiogram, contrast material that is not radioactive is injected into the heart arteries so the arteries can be seen by the x rays.

In some cases, if narrowed or blocked arteries are found during the exam, a procedure called angioplasty might be done to clean out the blockage and a metal stent placed in the artery to hold it open.
