In this work, the inversion recovery sequence was optimized for T1 measurements, by varying both the inversion recovery time (ti) and pre-delay (td). Comparing to conventional acquisition scheme, which uses logarithmic spacing ti and long td (> 5T1), the optimized sequence has precision efficiency of ~ 2.5 times greater than the conventional scheme.
