A patient receiving an MRI test

Our magnetic resonance imaging (MRI) service is located at the hospital’s KW Campus at 835 King Street West in Kitchener. We are located in the medical imaging department on the second floor of the hospital’s D wing. We operate 24 hours, seven days a week.

Magnetic resonance imaging uses a strong magnet and radio frequency waves combined with a powerful computer system to produce internal scans of the body.

In support of local academia, we have partnered with the University of Waterloo to provide after-hours access to the MRI for research purposes. This partnership has allowed us to enhance our equipment to improve scan times and image quality. It has also provided new MRI functions to support brain research.

For more information on our MRI service, please call 519-749-4262.
