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.
