Stroke MRI at Oxford


It has been a while since I have updated Spotlight-On-Science with a new posting. I have been busy working at the University of Oxford on a research position combining advanced computer applications and MRI.


 
While the group I have joined has many research projects, a particularly interesting aspect of our research is looking at whether a new way of using MRI magnets, called pH-weighted MRI is useful for assessing stroke patients. Patients with an ischaemic stroke have reduced blood flow to the affected areas of the brain, as the standard supply of energy from the blood is cut off anaerobic processes are increasingly relied upon for ATP production. Lactic acid is a byproduct of anaerobic processes and using pH weighted MRI our lab has managed to image tissue acidosis in acute stroke patients.

A large amount of my research to date has been focused on breast cancer detection from MRI examinations and I've brought that work with me so that I can continue it part time. I've wanted to work in brain imaging for a long time as the brain is the most physiologically interesting organ.
