Statistical analysis of global MD based on all six ex vivo datasets using LR Only, CS Only and LR/CS. (a) p-value analysis between reference and reconstructed global MD at acceleration factors of R=2.0, 4.0, 6.0, 8.0, 10.0, 12.0, 16.0 and 20.0. The significance level (P=0.05) is labeled in red. (b) The intra-class correlation coefficient analysis between reference and reconstructed global MD. (c) Normalized bias between reference and reconstructed global MD.
