Abstract
A shortened version of the MOLLI sequence (Sh-MOLLI) is described which generates rapid and high-resolution myocardial spin-lattice (T1) maps. The Sh-MOLLI technique is based on a significant abbreviation of pre-existing TI sampling scheme combined with the use of processing logic to bypass the major side effects of the above sampling scheme abbreviation and distinguish between long and short T1 relaxation times in order to conditionally utilize available TI samples for non-linear T1 fitting.
