Area of Science:

  • Neuroimaging
  • Artificial Intelligence in Medicine
  • Medical Informatics

Background:

  • Alzheimer's disease (AD) diagnosis is critical at the Mild Cognitive Impairment (MCI) stage.
  • Physicians require similar case examples for evidence-based diagnosis and clinical reasoning.
  • Existing automated diagnosis methods lack robust case retrieval capabilities.

Purpose of the Study:

  • To develop a multi-graph learning based medical image retrieval technique for MCI diagnostic assistance.
  • To enable physicians to access visually similar MCI cases for clinical decision support.
  • To improve the accuracy and efficiency of MCI case retrieval.

Main Methods:

  • A two-stage approach involving query category prediction and ranking using multi-graph learning.
  • Formulating query and database subjects into multi-graph structures to learn relevance.
  • Utilizing MRI data (T1, DTI, ASL) from MCI subjects and normal controls for evaluation.

Main Results:

  • The proposed method achieved an average of 3.45 relevant samples within the top 5 retrieved results.
  • Demonstrated significant outperformance compared to baseline retrieval methods.
  • Successfully provided physicians with relevant reference cases for MCI diagnosis.

Conclusions:

  • The multi-graph learning approach offers a powerful tool for medical image retrieval in MCI diagnosis.
  • This technique enhances diagnostic assistance by providing clinically relevant case examples.
  • The method shows promise for improving diagnostic accuracy and supporting evidence-based medicine in neurology.
