Table 1. RMS error of reconstruction in a computational phantom.
Results from the computational study utilizing four FSE images (at SNR = 60) for each method. The labels, such as Fourier-EPG + EP, denote the method of reconstruction (Fourier transform or model-based fitting), the decay model used in the fit (EPG or exponential, EXP), and the k-space view ordering (CC, EP, or VT). ME-CAMBREC provided lower RMS errors in T2 estimates than any other method except echo prepared FSE fit to an exponential decay curve.
