Spearman’s rank correlation coefficients between QSM and neuropathologic measurements

	QSM
	Ventromedial	Dorsomedial	Ventrolateral	Dorsolateral
Pigmented neuron density	− 0.014 (P = 0.92)	− 0.35 (P = 0.007)	− 0.26 (P = 0.050)	− 0.26 (P = 0.053)
Non-pigmented neuron density	0.085 (P = 0.53)	0.055 (P = 0.68)	0.066 (P = 0.63)	0.026 (P = 0.85)
Tau %AO	0.45 (P = 0.002)	0.26 (P = 0.087)	0.23 (P = 0.13)	0.18 (P = 0.23)
Iron %AO	0.41 (P = 0.002)	0.45 (P =  < 0.001)	0.56 (P =  < 0.001)	0.56 (P =  < 0.001)

QSM values were adjusted for age and time from scan to death

Bold values indicate statistical significance at p < 0.05

%AO, percent area occupied; QSM, quantitative susceptibility mapping
