This study proposes a rapid and accurate MR fingerprinting (MRF) framework based on inversion-recovery turbo spin echo (IR-TSE) sequence. Compared with the conventional quantitative imaging method and FISP-MRF, the proposed one can provide T2 maps with high accuracy in addition to T1 and proton density (PD) for whole brain in about 6 minutes. In this regard, this new MRF strategy would potentially aid in achieving high resolution quantitative mapping for T2-sensitive circumstances such as epilepsy and multiple sclerosis applications.
