We propose an improved MR fingerprinting which can generate T1, T2, and T2* maps simultaneously. This method is based on single-shot EPI and signal acquisition consists of dual-stage divided by fixed and variable echo time. Dictionary generation and pattern matching were also modified in accordance with acquisition scheme. The feasibility of proposed method was demonstrated by phantom study and the MRF results are well correlated with the conventional T1, T2, and T2* maps. In-vivo brain MRF was also performed with a healthy volunteer.
