Increasing the field strength seems promising for high-resolution skin imaging but a legitimate concern is the increase in the spin-lattice relaxation parameter T1. Skin T1 maps at 1.5T, 3T, and 7T are compared and a novel non-linear least-square approach for fast and accurate T1-estimation is proposed.
