Monte Carlo simulations. (a) The effect of SNR on biexponential estimation (b) Acquiring scan at more Tsl timepoints reduces the estimation error. (c) The smaller short component (T1ρ,s) has less estimation error, (d) higher short fraction leads to a smaller error in estimating short component. (e) The shorter long component has more estimation error. (f) Higher long fraction leads to a smaller error in estimating long component.
