Magnetic Resonance Fingerprinting (MRF) is a technique which produces multiple parametric maps during a single fast acquisition. Before MRF can be adopted clinically, quantitative values derived from these maps must be proven accurate and reproducible over a range of T1 and T2 values and temperatures. The aim of this study was to investigate the accuracy and reproducibility of T1and T2 values derived from two different methods of MRF compared to conventional quantitative maps using the ISMRM/NIST system phantom.
