Correction of magnetization transfer saturation maps optimized for 7T postmortem MRI of the brain
PurposeMagnetization transfer saturation (MTsat) is a useful marker to probe tissue macromolecular content and myelination in the brain. The increased B1+ inhomogeneity at 7T and significantly larger saturation pulse flip angles which are often used for postmortem studies exceed the limits where previous B1+correction methods are applicable. Here, we develop a calibration-based correction model an
