Scientists will see the human nervous system in microscopic detail thanks to the installation of Canada’s first 7-Tesla whole-body magnetic resonance imaging (MRI) scanner on Feb. 5.

The new MRI scanner is capable of taking high-resolution images at pixel dimensions measured in tenths of a millimetre. The unit tesla refers to the power of the MRI’s magnet. Images from the more common 3-Tesla MRIs become extremely grainy at less than one millimeter, making the 7T considerably more powerful.

The introduction of the whole-body 7T MRI to The Neuro (Montreal Neurological Institute and Hospital) of McGill University will give researchers an unprecedented window into the effects of neurological disease not just on the brain, but the entire human nervous system. Some neurological and metabolic disorders affect the muscles and spine as well as the brain, and the new system will provide enhanced opportunities for studying such conditions throughout the body.

Specifically, the 7T MRI scanner will provide:

  • More powerful functional MRI, which shows the localization of specific brain functions and how different brain areas work together.
  • Detailed microstructural images that are of great value in the study of neurological disease.
  • More sensitive characterization of biochemical processes in tissues throughout the body.

“In 1985 The Neuro was the first institution in Canada to install an MRI,” says Dr. Guy Rouleau, Director of The Neuro. “This latest addition to our brain imaging capabilities maintains our status as a world leader in the field and more importantly will allow our scientists to uncover the fundamental knowledge of the brain we need to develop better treatments that benefit patients with neurological disease.”

“7T MRI has very recently been approved for clinical diagnosis in the United States and Canada. Research and development conducted at The Neuro will have an even greater impact thanks to the anticipated clinical adoption of such systems in the future,” says Richard Hoge, researcher and Director of the MRI Unit at The Neuro

Planning for the 7T MRI began in 2008 during the design phase of The Neuro’s new North Wing, which was constructed with an MRI suite capable of bearing the 70-tonne combined weight of the MRI scanner and its shielding. In 2015, a group of The Neuro’s researchers led by Amir Shmuel received an $18.8M grant from the Canada Foundation for Innovation, the Quebec Government’s Ministry of Economy and Innovation, and corporate partners such as the MRI manufacturer, Siemens Canada.

“This is the first of several major acquisitions planned for The Neuro over the next few years that will increase our capacity to support neuroscience research with cutting-edge brain imaging systems,” says Julien Doyon, Director of the McConnell Brain Imaging Centre.

Housed at The Neuro’s McConnell Brain Imaging Centre (BIC), the 7T will support multiple provincial, national and international projects and collaborations, including McGill’s “Healthy Brains for Healthy Lives” initiative, which seeks to link neurological health with overall wellbeing. Data collected by the 7T will be shared with the greater scientific community through The Neuro’s open science policy.
