Improved cardiac T mapping accuracy and precision with a new hybrid MOLLI and SASHA technique: MOSHA.

Purpose: To develop and validate a new myocardial T mapping sequence (MOSHA) which is based on a combination of the modified Look-Locker inversion recovery (MOLLI) and the saturation recovery single-shot acquisition (SASHA) sequences.

Methods: Prior studies have shown that myocardial T mapping by SASHA is more accurate but less precise than MOLLI. A new myocardial T mapping technique (MOSHA) based on single-shot acquisitions is developed by combining the MOLLI and SASHA sequences.
