Nuclear Adenosine Imaging
What is this test?
This is a nuclear test that monitors the heart to determine if the heart is not getting enough blood after a special medicine, called adenosine, has been given in the vein. The test uses a nuclear tracer to see blood in the heart muscle using a large, special camera that you lie under. The tracer is injected into an arm vein twice to see whether blood is entering all parts of the heart muscle at rest and after adenosine has been given. These pictures are recorded into a computer and later interpreted by a physician.
How is this test performed?
An intravenous (IV) is started in your arm and nuclear tracer will then be injected into your veins. After a short wait, you will lie on a stretcher under a special camera for about 15 minutes so that resting pictures of your heart can be obtained. After the resting pictures are obtained, electrical wires, called electrodes, are painlessly stuck onto your skin. Adenosine will be given into your arm veins over a 6 minute period. Three minutes after starting the adenosine, a nuclear tracer will again be injected into your arm vein. After the adenosine has been stopped, more pictures of your heart will be obtained.
What will it show?
The test will show the function of your heart at rest and after adenosine has been given. Normally the heart beats gets all the blood it needs at rest and after adenosine has been given. The test will show if part of your heart is not getting enough blood with adenosine. Changes in your electrocardiogram and heart rhythm will also be recorded and noted by the cardiologist.
Patient preparation and recovery
Please have a list of your medications available and bathe prior to the test as you will need to completely disrobe from the waist up. With the exception of deodorant, please do not apply lotions, oils, powder, or perfumes after bathing. A hospital gown will be provided for women or as needed.

It is also advisable to go to the restroom just before the test so that you not be distracted by this need during the test. Do not take any caffeinated product for 24 hours prior to the exam. This includes coffee, tea, chocolates, other candies, and Theophyllin, Persantine, and caffeine containing medications (such as Anacin, Excedrin, No-Doze, Vivarin). Fasting is required 6 hours prior to the test, though medications can be taken with sips of water. Do not have anything by mouth for 2 hours prior to the exam, including water. If you do not follow these strict requirements, the test will be rescheduled. Do not smoke or use any tobacco or nicotine containing product. No special recovery is needed.
