Figure 7. Sampling Dependent aSNR and $\text{a}{\mathrm{T}}_2\mathrm{*}$ Changes across Individuals.

(a) Sampling level vs percent difference in aSNR (a) and $\text{a}{\mathrm{T}}_2\mathrm{*}$ (c) in an individual mouse. Maximum percent difference for both metrics occurred at 10% sampling where aSNR decreased by 5.2% and $\text{a}{\mathrm{T}}_2\mathrm{*}$ increased by 2.5%. Sampling level vs percent difference in aSNR (b) and $\text{a}{\mathrm{T}}_2\mathrm{*}$ (d) for full population. Again, the maximum percent difference was at 10% sampling, where population aSNR decreased by 5.7% and $\text{a}{\mathrm{T}}_2\mathrm{*}$ increased by 4.0%. The statistically significant divergence (p < 0.05) in $\text{a}{\mathrm{T}}_2\mathrm{*}$ values from fully sampled images is below 80% sampling (red dashed vertical line).
