Abstract
3D multi-gradient echo MRI can be used to estimate T , T *, PD and the magnetization transfer (MT), which is increasingly used for multi-parametric
mapping (MPM) of human brain. The increased polarization at 7T compared to lower B allows for increased spatial resolution or reduced scan
times. However, SAR restrictions imposed on the MT pulse and B inhomogeneity pose challenges. In this work, we propose a protocol for MPM of
human brain at 7T with special attention paid to eliminating bias when mapping MT saturation while obtaining sub-millimeter isotropic spatial resolution in
under 12 minutes with acceptable SNR.
