New Graph Neural Network Model Aids Alzheimer's Diagnosis Using MRI Data

Researchers have developed a novel Multi-View Masked Graph Neural Network (MVMGNN) for diagnosing Alzheimer's disease using structural magnetic resonance imaging (sMRI). This model addresses limitations of existing methods by employing a joint node-edge masking mechanism to select relevant radiomics features and structural connections, thereby reducing redundancy in graph learning. A cross-view gated fusion mechanism is also utilized to integrate multi-view representations. Experiments conducted on the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset showed that MVMGNN achieved superior performance compared to several existing approaches in AD classification, with interpretability analysis highlighting its ability to identify key brain regions associated with the disease.
