Our Nuclear Medicine Technologist will administer an injection containing a slightly radioactive tracer, which is absorbed by your heart muscle. There are no side effects from this tracer and it contains only a small amount of radiation.

You will then be asked to sit and wait for 30-40 minutes while the tracer travels to the heart. After this time, imaging of your heart will commence for 20 minutes. For the next stage of examination, your heart rate is required to be raised so we can image your heart after it has been working harder than normal. To do this, we will ask you to walk on a treadmill. If you are unable to walk on the treadmill, we will issue a medicine that simulates you doing this exercise. Again, you will be asked to wait for 30-40 minutes before another 20 minutes of imaging commences.

Our Nuclear Medicine physician will review the images and issue a report. Once completed, the report will be sent electronically to your referring health professional.
