Magnetic Resonance Fingerprinting (MRF) provides simultaneous MR multi-parametric maps. Purpose of this work is to reduce the number of TR/FA and to obtain optimal combinations. PSIF sequence was used to obtain 3D plots for different brain tissue types and a difference plot of GM and WM were generated. 48 TR/FA (through sample size analysis) values were picked from difference plot to achieve high CNR and T1 and T2 maps were obtained by pattern matching algorithm. Mean and Standard deviation of T1 and T2 values for WM, GM, and CSF were calculated that lie in the standard range.
