T1 mapping provides useful information for quantitative
MR. Gold-standard method using inversion recovery spin
echo sequence is robust but slow. EPI readout together
with simultaneous multi-slice excitation can greatly
accelerate the acquisition, and using a slice-shuffled
method can accelerate the sampling of the T1 recovery.
Here we test and validate fast T1 mapping methods using
a combination of simultaneous multi-slice excitation to
accelerate the cross-slice acquisition, in-plane
acceleration to shorten the readout, and slice-shuffling
to achieve rapid T1 recovery sampling.
