Association of temporal cingulum fixel metrics with PET biomarker findings. The correlation matrix is coloured by Spearman correlation coefficients and significance is indicated by *P < 0.05, **P < 0.01, ***P < 0.005, uncorrected for multiple comparisons. CompVOI = composite volume-of-interest; FC = fibre cross-section; FD = fibre density; FDC = fibre density and cross-section; HpC = hippocampus; PCC-P = posterior cingulate cortex and precuneus; L = left; R = right
