Stress Test With Nuclear Imaging

If you are, or think you may be pregnant, please inform the technologist. 

Your doctor has requested a stress test with nuclear myocardial imaging. This test takes place in the Testing Lab in our office under the supervision of the cardiologist.  A specially trained cardiac technologist will perform the testing with the doctor.

The first part of the test involves administration of a tracer followed by imaging of your heart ("rest images").

The second part of the test involves exercising comfortably on a treadmill, with administration of a second dose of tracer, followed by a second set of images ("stress images").  

If you cannot exercise on a treadmill, your doctor will order a "pharmacologic" stress test.  You will not exercise on a treadmill in this case.  Instead, Regadenoson will be administered during the second part of the test to prepare you for the "stress images".

The data is then processed and analyzed by a specially trained physician to determine if there is coronary artery disease present.  Overall heart function and the presence of a previous heart attack (myocardial infarction) is also appreciated on this test.  This test may also be used for patient evaluation after treatment of coronary artery disease, such as after a coronary artery bypass or stenting procedure.

Your test may take place all in one day.  In certain circumstances, to improve image quality, your test may take place over two consecutive days.  This will be determined when your appointment is set up.  A one-day test takes approximately three hours to complete.  A two-day test takes approximately one and a half hours each day to complete. 

Preparations for this test are very important. Please follow the instructions EXACTLY

  1. Please do not eat or drink for four (4) hours prior to the test. Small sips of water may be taken with medications. 
  2. No caffeine of any kind for 12 hours prior to the test.  Please note that "decaffeinated" beverages may contain residual caffeine and should be avoided.  Chocolate should also be avoided.
  3. Do not smoke for four (4) hours prior to the test. 
  4. Take your medications as usual on the day of the test unless your doctor instructs you otherwise.
  5. Please bring a list of your medications, your insurance card, and your co-pay (if any) to your appointment.
