Novel imaging technique captures the effects of COVID-19 on the brain
A University of Waterloo engineer's MRI invention reveals better than many existing imaging technologies how COVID-19 can change the human brain.
The new imaging technique known as correlated diffusion imaging (CDI) was developed by systems design engineering professor Alexander Wong and recently used in a groundbreaking study by scientists at Baycrest’s Rotman Research Institute and Sunnybrook Hospital in Toronto.
Researchers at Rotman, saw Wong’s imaging discovery and thought it could likely also be used to identify changes to the brain due to COVID-19. Subsequent tests proved that theory right. The CDI imaging of frontal-lobe white matter revealed a less restricted diffusion of water molecules in COVID-19 patients. At the same time, it showed a more restricted diffusion of water molecules in the cerebellum of patients with COVID-19.
