Myocardial Perfusion Imaging Treadmill Test

This test takes approximately 4 1/2 hours.

A Myocardial Perfusion Imaging Treadmill test uses a radioactive substance (not a dye) to produce pictures of the heart muscle.  The radioactive substance gives off a small amount of radiation which can be seen with a special camera.  The amount of radiation exposure during this test is very small and poses no health risk.  The test will help your doctor determine if there are areas of your heart which do not receive enough blood supply due to coronary artery disease.  Areas of your heart which may have been damaged from a previous heart attack may also be seen.  Prior to the test an IV will be started.  During the rest portion of the test, you will receive an injection of the radioactive substance, and pictures will be taken of your heart.  For the stress portion of the test, you will walk on a treadmill and be continuously monitored for blood pressure, heart rate, rhythm and ECG changes.  You will be given an injection of the radioactive substance during your last minute of exercise.  Following the treadmill, pictures will be taken to determine blood flow to the heart muscle.
