Description
3D multi-gradient echoes can be used to estimate T1, T2*, PD and the magnetization (MT), which is increasingly used for multi-parametric mapping (MPM) of human brain. The increased polarization at 7T compared to lower B0 allows for increased spatial resolution or reduced scan times. However, SAR restrictions imposed on the MT pulse and B1 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 MTsatwhile obtaining submillimeter isotropic spatial resolution in under 12 minutes with acceptable SNR.
