Research areas description
About one-third of Canadians will be affected by a disease, disorder or injury of the brain or the spinal cord during their lifetime. Magnetic resonance imaging (MRI) is the method of choice for diagnosing most of these diseases. But MRI resolution is on the order of millimeters when the pathological changes it is detecting are on the scale of micrometers. That means clinicians lack important information: Are certain connections in the brain still there? Are certain neurons still working?
As chairholder of the Canada Research Chair in Quantitative Magnetic Resonance Imaging, Dr. Julien Cohen-Adad is trying to answer these questions. He and his research team are developing new technologies that can see even further into the complex architecture of the human nervous system. For example, by combining powerful biophysical models with advanced image processing tools, they can "see" the state of health of our neurons from simple MRI images.
Dr. Cohen-Adad has established a wide network of researchers and clinicians with whom he shares his tools. He also trains hospital staff, so that these new technologies can be used every day to directly benefit Canadians suffering from a range of diseases that affect the central nervous system.
Along with benefiting clinicians and their patients, this research will also enable researchers and pharmaceutical companies to test the effectiveness of new drugs, such as those aiming to repair neuronal tissue in multiple sclerosis.
