Research Focus

The research activities of the Cardiovascular Magnetic Resonance (CMR) Research Centre at the McGill University Health Centre focus on novel techniques that permit the optimization and simplification of clinical CMR protocols that require minimal interaction and reduce the need for contrast agents or stress protocols. This includes the application of novel CMR image reconstruction techniques, machine learning, automated scanning, and the validation of novel imaging biomarkers in clinical studies. Several current projects explore new options for assessing coronary vascular function, using breathing manoeuvres instead of traditional pharmacological vasodilators or stress protocols as vasoactive triggers. The CMR Research Team aims for new knowledge that can significantly change diagnostic cardiology. The team has access to two clinical MRI scanners (Siemens Skyra 3.0T, GE Artist 1.5T) and full-time access to a dedicated MRI system (GE Premier 3.0T) for CMR research. The most significant support for the research program comes from the Family Courtois Foundation through the McGill University Health Centre Foundation. There is a close collaboration with invasive and non-invasive cardiology, cardiac surgery, and radiology teams. The team also has active collaborations with other hospitals in Montreal, as well as with other academic centres in Canada and worldwide, including cohort research with the Canadian Alliance for Healthy Hearts and Minds.
