Background:

Brain network analysis is crucial for diagnosing brain diseases.
Integrating multiple neuroimaging modalities enhances analysis but existing methods often miss unique data characteristics.
Current approaches struggle to fully leverage complementary and unique information from diverse imaging sources.

Purpose of the Study:

To propose a novel method, Beta-Informativeness-Diffusion Multilayer Graph Embedding (BID-MGE), for enhanced brain network analysis.
To effectively integrate structural connectivity (SC) and functional connectivity (FC) for improved diagnosis of neuropsychiatric disorders.
To address limitations in existing multimodal brain network analysis methods.

Main Methods:

Developed Beta-Informativeness-Diffusion Multilayer Graph Embedding (BID-MGE) integrating SC and FC.
Utilized a novel beta distribution mapping function to refine connectivity information.
Employed an optimal scale multilayer brain network with node informativeness-dependent inter-layer connections.
Implemented multilayer informativeness diffusion to capture modality-specific and complementary features.
Applied principal component analysis (PCA) and cosine distance for classification.

Main Results:

The BID-MGE method effectively integrates complementary and unique information from SC and FC.
The method successfully identifies crucial brain regions associated with neuropsychiatric disorders.
BID-MGE demonstrated superior classification performance compared to advanced existing methods.

Conclusions:

The proposed BID-MGE method offers a powerful approach for multimodal brain network analysis.
BID-MGE provides valuable insights into the pathology of neuropsychiatric disorders.
This method enhances diagnostic accuracy for brain diseases through integrated neuroimaging analysis.
