Abstract
Background Myocardial T1 mapping is emerging as a promising means to non-invasively discriminate between normal and diseased myocardium. Original modified Look-Locker sequence (3’3’5-MOLLI) can induce a long breath-hold and is prone to cardiac and respiratory motion. Several shorter sequences (3’5MOLLI, shMOLLI and SASHA) have been proposed for acquisition of T1 values. We examined native and postcontrast T1 values derived by above sequences within the same subject and investigated their ability to separate between health and disease. We further examined reproducibility of measurements within and between observers.

Myocardial T1 mapping is emerging as a promising means to non-invasively discriminate between normal and diseased myocardium
We examined native and postcontrast T1 values derived by above sequences within the same subject and investigated their ability to separate between health and disease
T1 values were quantified within the septal, lateral myocardium and LV blood pool
