Artificial Intelligence and Machine Learning for Osteoarthritis and Cartilage Assessment

Area of Science:

• Musculoskeletal Radiology
• Medical Imaging Analysis
• Artificial Intelligence in Medicine

Background:

• Osteoarthritis (OA) is a prevalent global condition impacting over 500 million individuals.
• OA presents significant diagnostic and management challenges due to its intricate pathophysiology.
• Advancements in artificial intelligence (AI), especially deep learning, are transforming medical imaging analysis.

Purpose of the Study:

• To evaluate the application of AI in radiograph analysis for osteoarthritis.
• To assess AI's role in MR imaging for cartilage evaluation and OA scoring.
• To review AI-driven enhancements in musculoskeletal radiology for OA.

Main Methods:

• Review of AI applications in radiograph analysis, including Kellgren-Lawrence grading and segmentation.
• Evaluation of AI techniques for MR imaging tasks: sequence optimization, rapid acquisition, and denoising.
• Analysis of AI in cartilage measurement and OA scoring systems (WORMS, MOAKS, WOMAC).

Main Results:

• AI significantly improves the accuracy and efficiency of radiograph analysis for OA.
• Deep learning enhances MR imaging interpretation for cartilage assessment and OA staging.
• AI facilitates objective and reproducible scoring of OA using established systems.

Conclusions:
