The best way to ensure radiation safety is to reduce or eliminate unnecessary testing, and employing the appropriate use criteria can help in this area, said Dr. Robert Hendel, director of cardiac imaging and outpatient services at the University of Miami Miller School of Medicine. Speaking at the American Society of Nuclear Cardiology meeting in Denver, Hendel said that it is still difficult to pinpoint when tests are being overused, underused or appropriately used, but one area to watch out for is serial testing, since it is during these series of tests that patients are exposed to higher doses of radiation.
