Pseudo replica coefficients of variation (CVs) and within-session repeatability of MRF T1 and T2 measurements in 4 healthy volunteers. For each tissue type, T1 and T2 was calculated from 3D regions-of-interest. The mean ± standard deviation (SD) across subjects is reported for the repeated measures CV and the Bland-Altman bias is calculated from the group.

		Pseudo-replica CV	Repeated measures CV (mean ± SD)	Bland Altman Bias ± 1.96 SD
White Matter	T1	0.008%	0.76 ± 0.35%	1.5 ± 12 ms
	T2	0.014%	3.8 ± 5.0%	−1.9 ± 6.1 ms
Gray Matter	Tl	0.007%	0.7 ± 0.5%	5.0 ± 19.1 ms
	T2	0.009%	3.8 ± 5.2%	−2.8 ± 10.9 ms
Cerebrospinal fluid	T1	0.011%	2.5 ± 1.7%	6.0 ± 236.1 ms
	T2	0.028%	3.5 ± 0.6%	1.4 ± 57.9 ms
