TABLE II.

Sample means ± sample standard deviations of T₁ and T₂ ML estimates in WM and GM ROIs of simulated data, compared across different optimized scan profiles. Sample means exhibit insignificant bias, and sample standard deviations are consistent with worst-case standard deviations ${\tilde{σ}}_{T_{1}}^{t}$ and ${\tilde{σ}}_{T_{2}}^{t}$ reported in Table I. All values are reported in milliseconds.
