This work evaluates repeatability of T₁ and T₂ estimation of the TMRF method compared to MRF and the gold standard measurements at two sites. In this work, we acquired data for 10 days on ISMRM/NIST phantom using the three methods at the two sites with the same vendor and field strength. The data was reconstructed and matched with an EPG simulated dictionary. ROI analysis was performed to extract T₁ and T₂ estimation for each sphere. The results and statistical analysis are presented here.
