The spin-lattice relaxation time (T1) of tissues can be estimated from a set of T1 weighted images. Even though T1 mapping has a broad range of potential applications, T1 maps are not routinely used in clinical practice. The high acquisition time of the necessary set of high resolution T1 weighted images is not clinically feasible. We propose to use super-resolution in combination with T1 estimation to provide a better trade off between the acquisition time, SNR and spatial resolution of the T1 maps.
