Predicting Dementia Severity by Merging Anatomical and Diffusion MRI with Deep 3D Convolutional Neural Networks

Tamoghna Chattopadhyay, Amit Singh, Neha Ann Joshy…·the Alzheimer’s Disease Neuroimaging Initiative

This paper uses deep 3D CNNs combining anatomical and diffusion MRI to predict dementia severity and brain age, finding that diffusion MRI improves performance over anatomical MRI alone.
