There is a significant need for specific biomarkers of myelin damage and repair. Quantitative magnetization transfer (qMT) using selective inversion recovery (SIR) is able to quantify the macromolecular-to-free proton pool size ratio (PSR), which has been shown to relate closely with myelin content and disability. For clinical applications, SIR is often hampered by long scan times. As a result, we employed compressed sensing and parallel imaging to significantly reduce scan times, with little effect on the precision and accuracy of PSR estimates in white matter.
