This study focused on the stability of MRF in a phantom and
volunteers, and explored the feasibility of MRF with a shorter acquisition
time. Phantom scans on 40 days and volunteer scans on 5 days over 3 months showed
comparable repeatability and reproducibility of T1 and T2 values between MRF
with acquisition times of 41 sec and 20 sec. Shorter acquisition time has the
potential to expand the clinical usage of MRF.
