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.
