Background radiation is radiation that does not contribute to the study or is not accumulated in the area of interest. In a perfusion exam, the radioactivity that is still circulating in the blood or in the organs near the myocardium is considered background radiation. The more radiation that exists outside of the area of interest, the poorer the quality of the image.
