Brain Imaging Centre

Brain Imaging Centre

The Royal's Brain Imaging Centre is a state-of-the art research facility featuring a positron emission tomography-magnetic resonance imaging (PET-MRI) machine -- the first of its kind in Canada dedicated solely to mental health and neuroscience research.  With brain imaging, we are making important strides towards making the invisible visible when it comes to mental illness; demonstrating that like any other medical condition, depression and related mental health disorders have an objective biology.
