SPECT locates areas of the heart muscle that have
inadequate blood flow compared with areas that have normal flow. Inadequate blood
flow may mean that coronary arteries are narrowed or that a heart
attack has occurred.
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.
