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.
