Diagnostic performance of APTw values from four regions of interest (ROIs) in predicting aMCI.

ROIs	AUC; [95% CI]	Cutoff value (%)	Sensitivity (%)	Specificity (%)
Right hippocampus	0.858; [0.799, 0.918]	0.842	87.1	73.0
Left hippocampus	0.836; [0.769, 0.903]	0.858	87.1	68.9
Right amygdala	0.838; [0.774, 0.902]	0.850	67.1	91.9
Left amygdala	0.875; [0.817, 0.933]	0.850	74.3	91.9

APTw, amide proton transfer-weighted; aMCI, amnestic mild cognitive; AUC, area under the ROC (receiver operator characteristic) curve; CI, confidence interval.
