Effect of number of principal component coefficients on T2 estimation. a Ground truth T2 map obtained by simulating the MB-DIR-RADFSE pulse sequence using the MRXCAT phantom [31]. Monte Carlo simulations were performed to evaluate the T2 estimation error in terms of the number of principal components (PC) retained during reconstruction. b Percent error maps of the myocardium when data is reconstructed using 2,3,4, and 5 PCs. The mean percent error values are also indicated
