Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

Please bring with you a list of your current medications. This includes prescription medications, over-the-counter medications, vitamin or mineral supplements and herbal remedies.
DO NOT eat 3 to 4 hours before the test, but you may have juice or water.
A friend or family member is required to be present in the lab during the test. They'll be instructed on how to care for you after the exam and required to drive and/or accompany you home. They can also help you gather information, take notes and ask questions.
When you arrive at the
Nuclear Cardiology Lab, check in at the reception desk. Please have the following ready:
When you check in, the receptionist will give you a name band to wear. The technologist will call you when it is time for your test. You will be asked to change into a hospital gown. There are lockers for your clothes in the change area, but you should keep your valuables with you.
When you have finished changing, a technologist will take you into the room. They will explain the procedure and ask for your consent.
A technologist will explain the test to you and ask about your medical history and medications. You'll then be given two needles about 20 to 30 minutes apart. The first injection is a preparation for the second injection which is the radioactive tracer. Then the technologist will do an
ECG and check your blood pressure and heart rate.
You'll be asked to lie down on a bed so a special camera can take pictures of your heart from 3 or 4 angles. Each picture takes 5 to 10 minutes, and it's very important that you don't move while these are being taken. Next, pictures will be taken while you pedal a bicycle. The bicycle tension will be increased every 3 minutes.
The supervising doctor may change some details in the procedures. The test might take longer if a scan needs to be done, emergency cases come to the department or there are unexpected results.
Once the test is completed, the technologist uploads your results to your records. The physician/radiologist will write a report and send it to your doctor.
The technologist cannot give you the results during your visit.
Once the report is in your health record, your doctor can review it. You will get the results of the test from your doctor.
The exercise MUGA takes about 90 minutes.
We do everything that we can to stay on time. Unfortunately, your appointment may be delayed by unforeseen circumstances. We recommend that you come prepared for delays.
