This study reports normative cardiac T₁ and T₂ values generated in a single cardiac MRF scan in a cohort of normal volunteers. These values were compared against MOLLI (for T₁) and bSSFP (for T₂). Our results show that cardiac relaxometry values obtained with MRF at 1.5 T are comparable to values previously reported in the literature and those obtained using MOLLI and bSSFP.
