Magnetic resonance fingerprinting (MRF) permits
non-invasive quantification of multiple important
properties simultaneously. In conventional MRF, an
acquisition time of approximately 10s is required for
each imaging slice. In this work, we developed a new
simultaneous multi-slice (SMS) technique to speed up MRF
acquisition. Specifically, we proposed t-blipped SMS-MRF
method, which utilizes additional Gz blip encodings to
provide phase modulation between the signals of
simultaneously acquired slices and creates
controlled-aliasing in the temporal axis. We
demonstrated the ability of t-blipped SMS-MRF technique
to accelerate MRF acquisition by 2-fold (MB=2) and
provide good parameter mapping at an acquisition time of
5s per slice using both simulation and in vivo
acquisition. We find that the t-blipped SMS technique
can speed up the MRF acquisition allowing a rapid
quantitative parameter mapping in a clinically relevant
time frame.
