Residual and Plain Convolutional Neural Networks for 3D Brain MRI Classification
This work addresses the need for more straightforward analysis in neuroimaging for Alzheimer's disease classification, but it is incremental as it applies existing CNN architectures to a known dataset.
The paper tackled the problem of classifying Alzheimer's disease, mild cognitive impairment, and normal controls from 3D brain MRI scans by skipping feature extraction steps, achieving similar performance to existing methods.
In the recent years there have been a number of studies that applied deep learning algorithms to neuroimaging data. Pipelines used in those studies mostly require multiple processing steps for feature extraction, although modern advancements in deep learning for image classification can provide a powerful framework for automatic feature generation and more straightforward analysis. In this paper, we show how similar performance can be achieved skipping these feature extraction steps with the residual and plain 3D convolutional neural network architectures. We demonstrate the performance of the proposed approach for classification of Alzheimer's disease versus mild cognitive impairment and normal controls on the Alzheimer's Disease National Initiative (ADNI) dataset of 3D structural MRI brain scans.
