Optimized Sodium Imaging of the Human Brain at 4.7 Tesla

Sodium images of the human brain are acquired using pulse-length and flip-angle optimization for SNR (considering a given scan duration) based on constant specific absorption rate. This optimization is performed using simulation with relaxation parameters measured in the human brain. Twisted projection acquisition is employed producing images with an acquisition voxel size of 3.2 mm isotropic at 4.7 Tesla in 10 minutes.
