Amyloid-β PET—Correlation with cerebrospinal fluid biomarkers and prediction of Alzheimer´s disease diagnosis in a memory clinic
Fig 2
ROC curves for CSF biomarkers and ratios with 18F-Flutemetamol PET as classifier.
The optimal cut-off value corresponding to the highest Youden´s index is given in the figure text. ROC, Receiver operating characteristic; CSF, Cerebrospinal fluid; PET, positron emission tomography; Aβ42, amyloid beta; T-tau, total tau; P-tau, phosphorylated tau; AUC, area under the curve; SS, sensitivity; SP, specificity; YI, Youden´s index.
