Results for biexponential T1ρ mapping error (MNAD) of the synthetic phantom, including (a) Cartesian with no noise in the acquisition, (b) radial with no noise, (c) Cartesian noisy (SNR=2.87), and (d) radial noisy (SNR=74.51), and also (e) MP-PCA filtered Cartesian noisy, and (f) MP-PCA filtered radial noisy. All MNAD values are computed comparing all parameters of the biexponential maps with ground truth.
