Also known as: MIBI, MPS, Thallium scan.

A Myocardial Perfusion scan evaluates coronary artery disease by assessing the blood flow to the heart muscle both at rest and at stress.

What happens during the procedure

Part 1: REST: You will be given a small injection of a radioactive tracer that is taken up by the heart muscle. This injection shouldn’t make you feel any different. Following a short wait (10-30 minutes), images will be acquired of your heart. This part of the test takes 30-60 minutes.

Part 2: STRESS: This involves exercise on a treadmill or bike. If you are unable to exercise an injection of medication is used to artificially stress the heart. An ECG is performed and your blood pressure is noted. Another injection of radioactive tracer is administered, this time with your heart at peak stress. After 20-60 minutes, more images will be acquire of your heart. This part of the test can take between 45-120 minutes.

How long does it take?

Allow at least 3 hours for completion of this examination.
