Table 1.

Simulated pseudodiffusion values compared with the true values and the percentage of outliers for different b-value distributions

	D_p = 20 μm²/ms			D_p = 40 μm²/ms			D_p = 60 μm²/ms			D_p = 80 μm²/ms			D_p = 100 μm²/ms
	Mean D_p	Med D_p	% Out	Mean D_p	Med D_p	% Out	Mean D_p	Med D_p	% Out	Mean D_p	Med D_p	% Out	Mean D_p	Med D_p	% Out
Low b=(0,50)	23	21	5.3	41	36	20.4	47	43	37.7	49	45	46.2	50	46	49.0
Low b=(0,25,50)	22	21	1.5	44	41	3.3	65	59	9.1	80	73	18.8	91	82	28.7
Low b=(0,10,25,50)	22	21	1.1	43	41	1.3	64	61	1.5	86	81	1.4	108	101	2.0
Low b=(0,10,25,40,50)	22	21	0.9	43	41	1.3	64	61	1.3	85	81	1.5	107	101	2.1

The units of the b-values are s/mm². True pseudodiffusion values are shown above of the simulated pseudodiffusion values. Each set of low b-values was in addition to a b-value distribution of b=(100,150,200,400,800) s/mm².

Abbreviations: D_p = Pseudodiffusion, % Out = Percentage of voxels excluded due to an ill-conditioned Jacobian matrix (i.e. percentage of outliers), Med = median.
