Our team of MRI Scientists works on the development of new imaging techniques and on the investigation of magnetic resonance signal generation in biological tissues. We are physicists within the departments of Physics and Astronomy, Pediatrics, and Radiology. Our specific interests are MR signal formation in the presence of magnetically inhomogeneous tissues, such as nerve fibres or blood vessels and the application of our new MRI techniques to the investigation of tissue damage and repair in brain injury due to preterm birth, multiple sclerosis, and traumatic brain injury. We collaborate with various researchers from the departments of Physics and Astronomy, Pediatrics, Radiology, Neurology, Pathology, and internationally.
News: Mapping cerebrovascular health
We have a gas control system (RespirAct™, Thornhill Medical) that allows us to map cerebrovascular reactivity using our MRI scanners. We can create maps of the brains vascular health that were shown to be useful in a wide range of conditions, such as Alzheimer’s disease, multiple sclerosis, or traumatic brain injury.
