It is a noninvasive imaging scan that exposes you to radiation. For this test, your doctor injects a tiny amount of radioactive tracers through a vein in your arm. After the radioactive tracer is injected, a camera that can detect the radiation emitted by these tracers rotates around you. This creates images of your heart from different angles. Then, computer graphics are used to create three-dimensional images of your heart.
