Mean signal intensities from Safranin-O stained histology sections of each animal vs. their average T_1ρ. Where =3-month, =5-month, and =9-month data. A moderate correlation (R²=0.44, p<0.01) exists but is improved (R²=0.67, p<0.01) if the outlier with abnormal and statistically significantly (z=−2.2) high stain intensity (indicated by dotted circle) is removed before analysis.
