temporal volume was associated with approximately 1.5 times (95% CI 1.1 to 2.0) greater risk of AD. The area under the ROC curve for FreeSurfer medial temporal, LEAP hippocampal, and Ab:tau (logarithmic) were 0.688, 0.604, and 0.572, respectively. Conclusions: We found that the 3 biomarkers (hippocampal volume, medial temporal lobe volume, and CSF Ab:tau) significantly and independently predict the development of AD from MCI. A particular level of Ab:tau ratio enhances the predictive accuracy of MRI biomarkers. These biomarkers are associated with different aspects of AD pathology.
