From: A deep learning MRI approach outperforms other biomarkers of prodromal Alzheimer’s disease
Classifying Alzheimer’s disease in its dementia stage. The “receiver operating characteristic” curve shows that the deep learning MRI score applied to the test set of Alzheimer’s disease (AD) dementia scans vs. healthy controls scans classified AD dementia with high accuracy (AUCROC = 0.973) (a). The class activation map, reflective of the regional contributions to the deep learning MRI scores, localized to the left anterior medial temporal lobe in the vicinity of the entorhinal cortex and hippocampus, where Alzheimer’s pathophysiology begins
