Nuclear Medicine

Nuclear medicine uses small amounts of radioactive materials to diagnose and treat a variety of diseases including several types of cancers, heart disease and other abnormalities.

Care We Provide

Our nuclear medicine team provides services for cardiology patients, including state-of-the-art myocardial perfusion imaging and radionuclide angiography.

Referral Process

All patients are referred through their family doctor or through a specialist that they may be seeing.


Positron Emission Tomography (PET) and Computed Tomography (CT)

PET and CT scans aid in the diagnosis, staging and treatment of disease by studying the function of organs in the body.

A PET scan looks at the biological activity of a tumour or abnormality. A CT provides multiple images of the inside of the body to help determine location, size and shape of whatever is being examined. A PET/CT scan combines the results of both types of scans and result in a more detailed picture of the diseased tissue.

Cardiac PET/CT: A non-invasive procedure that can identify areas of abnormal blood flow through the heart, and determine the functional capacity of your heart muscle. This helps doctors determine the severity of heart disease and decide what follow-up therapy or intervention is needed.

Oncology PET/CT: Imaging that allows doctors to better locate active tumours using a special radioactive sugar that targets the tumours. These scans can also help determine the success of a treatment overtime, and whether a change in treatment is needed.

PET/CT scans are done at St. Joseph’s Hospital in the Fontbonne Building.
