This is a two-part test which consists of a "Rest" portion, and a "Stress" portion. For the rest portion of the test you will be injected with a drug that contains a radioactive isotope. After about 30 minutes, you will lie down on an imaging table, and we will take "pictures" of your heart. lt takes about 15 minutes to complete these pictures.
For the stress portion of the test, you will walk on a treadmill until your heart rate is increased to a certain level, and you will then be injected with a second dose of the radioactive isotope. If you are unable to walk, your doctor may want to administer a drug that will achieve the same effect as walking on a treadmill. After the stress portion of the study, we will then take a second set of pictures that should also last about 15 minutes. Viewed together, your doctor can tell the condition of your coronary arteries, which are the blood vessels that supply blood to your heart muscle.
The whole procedure could take up to about 3 to 6 hours, but typically lasts about 3-4 hours.
