Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Orthopedics

Background:

  • Lumbar disc herniation (LDH) diagnosis relies heavily on Magnetic Resonance Imaging (MRI).
  • Current subjective clinical diagnosis and treatment lack reproducibility.
  • An objective, MRI-based decision support system is needed for consistent LDH evaluation.

Purpose of the Study:

  • To develop an MRI-based decision support system for lumbar disc herniation (LDH).
  • To enhance the reproducibility, consistency, and reliability of LDH diagnosis and classification.
  • To provide an objective reference for clinical diagnosis and treatment procedures.

Main Methods:

  • A machine learning system was developed and trained on a dataset of 217 patients' MRI scans (3255 lumbar discs).
  • The system analyzes radiological features to diagnose herniation and classifies discs using Pfirrmann grade and MSU classification.
  • Clinical advice is generated based on the system's assessment.

Main Results:

  • The diagnostic accuracy reached 95.83%.
  • Agreement with ground-truth was 83.5% for Pfirrmann grade and 95.0% precision for MSU classification.
  • The system substantially improved accuracy, interpretation efficiency, and interrater agreement among surgeons.

Conclusions:

  • The developed MRI-based decision support system demonstrates high accuracy and efficiency.
  • It serves as a valuable objective reference for diagnosing and treating lumbar disc herniation.
  • The system has the potential to significantly improve clinical practice for LDH management.
