Question

Quizplus · Accepted Answer

A radioactive tracer, such as Technetium-99m, is injected intravenously during a nuclear stress test to allow the heart to be viewed on a special camera. This tracer is taken up by the heart muscle and emits radiation that is detected by the camera, producing images of blood flow to the heart. Valium, digitalis, and beta blockers are not used as tracers in nuclear stress testing.
