Toronto, June 15 (Ians) Researchers have used a new type of magnetic resonance imaging (Mri) to probe 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 at University of Waterloo.
It was originally developed for detecting cancer. Cdi is a new form of Mri that can better highlight the differences in the way water molecules move in tissue by capturing and mixing Mri signals at different gradient pulse strengths and timings.
A team at Rotman Research Institute at Baycrest used the Cdi for Covid study on the brain.
Their findings, published in the journal Human Brain Mapping, showed that 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...

Toronto, May 29 (Ians) Researchers have developed an Artificial Intelligence (AI) technology that is capable of assessing the severity of Covid-19 cases with a promising degree of accuracy.
The researchers from the University of Waterloo and Alexander Wong, a systems design engineering professor and co-founder of software company DarwinAI, said the technology could give doctors an important tool to help them manage cases.
"Assessing the severity of a patient with Covid-19 is a critical step in the clinical workflow for determining the best course of action for treatment and care, be it admitting the patient to ICU, giving a patient oxygen therapy, or putting a patient on a mechanical ventilator," Wong said.
For the study published in the journal Scientific Reports, deep-learning AI was trained to analyse the extent and opacity of infection in the lungs of Covid-19 patients based on chest x-rays.
Its scores were then compared to assessments of...
