A Framework Utilizing Artificial Intelligence for Consistent Landmark Identification and Morphometric Analysis in Musculoskeletal Imaging
To develop a universal landmark-matching framework for automatic morphometric measurements from foot, knee, and shoulder radiographs, and to evaluate its accuracy against radiologists' inter-reader agreement using statistical methods.
Key Findings:
The dense-matching approach achieved a mean absolute error (MAE) of less than 3 mm for landmark localization across different anatomic regions, indicating high accuracy.
Inter-method variability approached inter-reader variability for most morphometric measurements, suggesting the framework's reliability.
The framework remained functional in the presence of orthopedic implants, with some variation in measurement accuracy, highlighting areas for further improvement.
Interpretation:
The AI framework demonstrates potential for standardizing landmark identification and morphometric analysis in musculoskeletal imaging, reducing reliance on manual processes and improving consistency.
Limitations:
The study was conducted at a single center, which may limit generalizability and applicability to broader clinical settings.
The framework's performance in extreme cases of anatomical variation or rare pathologies was not fully tested, potentially affecting its robustness in diverse clinical scenarios.
Conclusion:
The proposed AI framework offers a promising solution for automating landmark identification and morphometric analysis in musculoskeletal imaging, potentially enhancing diagnostic accuracy and efficiency.
