The objective of this study was to evaluate the accuracy
and precision of pseudorandom inversion recovery
balanced steady-state free precession magnetic resonance
fingerprinting (MRF) relaxometry (T1 and T2) estimates
over a range of SNRs and the number of acquired TRs
(NTR) using Bloch equation simulations. Under the
condition of perfect sampling, the Bloch simulations
defined a lower-bound acquisition requirement of SNR5
and NTR400 for accurate and precise T1 and T2
estimates when using MRF. This work also concluded that
MRF provides nearly equivalent T1 and T2 estimates.
