Monte Carlo simulations. Effect of different parameters on biexponential model. (a) The estimation mean-absolute percentage error (MAPE) decreases by increasing the number of TSLs. (b) Higher SNR leads to less estimation error. (c) The estimation is more accurate for shorter short component (T1ρs). (d) The estimation is more accurate for larger long component (T1ρl). (e,f) The component with larger fraction (short component, As, in (e) and long component, Al in (f)) has better estimation than the component with a shorter fraction.
