The Magnetic Resonance guided Radiation Therapy (MRgRT) suite at the Princess Margaret Cancer Centre is the first-of-its-kind in Canada. Our facility consists of a full strength, open bore magnetic resonance imaging device on rails, which moves between a linear accelerator and a High Dose Rate (HDR) brachytherapy suite. It is one of the few facilities in Canada where MR guided brachytherapy is available and the first facility containing HDR brachytherapy suite, MRI and linear accelerators in the same suite.
