Methods for Paramagnetic and Diamagnetic Susceptibility Separation

Recent advances in Magnetic Resonance Imaging (MRI) have enabled visualization of iron and myelin in the brain using a method that can measure the effects of MRI field changes. The physical property measured is called magnetic susceptibility, which can visualize iron accumulation in the brain and also myelin which is a wrapping around nerves. The partner organization has implemented software to detect this effect. However, this method cannot separate out the individual contributions of myelin and iron. In diseases such as Multiple Sclerosis, iron and myelin changes can happen at the same time, thus separating them out is very important. The research project will involve an expert in magnetic susceptibility who will test methods for susceptibility separation and develop best techniques for performing this task, then implement them on the partner’s MRI systems. The benefit to the partner will be new and proven reconstruction techniques to further advance MRI.
