2-Day MIBI Nuclear Perfusion Test

A test used to visualize the blood flow through the heart in both a resting state, and after physical activity.

This procedure is used to evaluate and image the blood flow to the heart muscle while in a resting state (no exercise) and in a ‘stressed’ state (exercised).
You will be required to have two appointments, one for the stress protocol and another for the rest protocol. They will not be done on the same day but can be done in either order.

Stress Test

How to Prepare for the Stress Test

Nothing to eat or drink two hours prior to test. Diabetes medications should NOT be taken on the morning of the test. Patients with diabetes will be given early morning appointments for the rest and stress studies. Please do NOT take the following medications two days prior to the Stress test:

  • All Beta Blockers and certain Calcium Channel Blockers
  • Acebutolol (Sectral)
  • Atenolol (Tenormin, Tenoretic)
  • Carvedilol
  • Diltiazem (Cardizem, Tiazac)
  • Labetalol
  • Metoprolol (Lopressor)
  • Monocor (Bisoprolol)
  • Nadolol (Corgard)
  • Pindolol (Visken)
  • Propranolol (Inderal)
  • Sotolol (Sotacor)
  • Timolol (Blocadren)
  • Verapamil (Isoptin, Chronovera)

What Happens During this Test

The stress protocol will be performed on a treadmill. While exercising, the workload on your heart will gradually increase. Once you have reached your age-predicted target heart rate you will be given an injection of a radioactive tracer called Cardiolite through a pre-established IV. The scan of your heart will take place about 30 minutes later. The total test time is 2 hours.

Resting Test

How to Prepare for the Stress Test

Nothing to eat or drink for four hours prior to test. All medications EXCEPT diabetes medications may be taken on the morning of the test with a small sip of water. Patients with diabetes will be given early morning appointments for the rest and stress studies. Please wear a loose fitting t-shirt with no metal or buttons.

What Happens During this Test

For the rest images of your heart, you will be given another injection of a small amount of Cardiolite. There are no major side effects to this material. Some people get a metallic taste in their mouths following administration. The Cardiolite tracer will accumulate in your heart muscle over the next hour. After the hour has passed, an image will be taken of your heart. This scan takes about 25 minutes. The total test time is 1 hour and 30 minutes but plan on 2 hours from arrival to the end of the appointment.
