Myocardial T₁ and T₂ relaxation times obtained with MRF were compared to values from traditional mapping sequences (MOLLI and T₂-prep bSSFP) and evaluated for repeatability and reproducibility in 50 normal volunteers, as per SCMR consensus guidelines. MRF compared favorably with traditional sequences without significant proportional or systemic differences with fair to excellent repeatability and reproducibility, while providing better image quality.
