Brain Imaging

216
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Area of Science:

  • Neuroimaging
  • Artificial Intelligence
  • Psychiatric Disorders

Background:

  • Mood disorders like bipolar disorder (BD) and major depressive disorder (MDD) have subjective diagnostic criteria, leading to potential misdiagnosis.
  • Understanding the neurobiological underpinnings of these disorders remains a challenge.
  • Structural magnetic resonance imaging (MRI) offers objective data but requires advanced analytical tools.

Purpose of the Study:

  • To develop and evaluate SE-ResNet, a deep learning framework for discriminating between BD, MDD, and healthy controls (HC) using structural MRI data.
  • To enhance feature discrimination by fusing channel and spatial attention mechanisms within a Residual Network (ResNet) architecture.

Main Methods:

  • Utilized a Residual Network (ResNet) architecture incorporating an enhanced Squeeze-Excitation (SE) layer with a spatial attention branch.
  • Implemented soft-pooling for downsampling to preserve feature richness, unlike traditional max-pooling.
  • Trained and validated the SE-ResNet framework on a proprietary dataset of 303 subjects.

Main Results:

  • The SE-ResNet model achieved high performance metrics: 85.8% accuracy, 85.7% recall, 85.9% precision, and 85.8% F1 score.
  • Demonstrated the framework's capability in distinguishing between BD, MDD, and HC groups.
  • The integrated channel and spatial attention mechanisms effectively enhanced feature discrimination.

Conclusions:

  • The SE-ResNet framework shows significant potential as an objective tool for the detection of psychiatric disorders using structural MRI.
  • This AI-driven approach could aid in improving diagnostic accuracy and understanding the neuroimaging correlates of mood disorders.
  • Further validation on larger, diverse datasets is warranted to confirm clinical utility.
