This procedure is also known as Thallium scan, Exercise Stress test, Dipyridamole Stress test or Dobutamine stress test.

Initially you will have a stress test (exercise or pharmaceutical) and during this you will be given an injection of a radiopharmaceutical.

After you have recovered from the stress test, images of you heart will be taken with a Gamma camera.

Most patients will then need to return for an additional injection of radiopharmaceutical approximately 2 hours later followed by images to show the heart at rest.

Before your Scan

No caffeine (tea, coffee, chocolate, cola drinks etc) for 24 hours prior to the test.

Wear clothing suitable for exercise.

Do not stop your medications unless instructed by your cardiologist.

Duration

2 hours for stress testing and images, plus 1 hour for rest images.
