Survey of AI-Powered Approaches for Osteoporosis Diagnosis in Medical Imaging

AI can improve early osteoporosis detection across multiple imaging types: The survey documents that artificial intelligence methods are successfully analyzing routine medical scans (DXA, X-ray, CT, and MRI) to identify subtle markers of osteoporosis that might otherwise be missed, potentially preventing fragility fractures before they occur.

Data scarcity and external validation remain critical barriers to clinical deployment: The review identifies that fragmented research across different imaging modalities and AI approaches has created gaps in data availability and limited testing of these AI systems across diverse patient populations—key requirements before these tools can be reliably used in real-world clinical settings.

Interpretability is essential for clinician trust and adoption: The survey emphasizes explainable AI as a core component of the framework, highlighting that for AI tools to be responsibly integrated into osteoporosis diagnosis, clinicians need to understand why the AI makes specific recommendations, not just accept its predictions.

Multiple AI approaches show promise, but standardization is needed: The paper synthesizes findings across classical machine learning, deep learning (CNNs, transformers), and self-supervised learning methods, suggesting that while diverse technical approaches work, the field lacks unified standards for comparison and evaluation that would help clinicians and researchers identify which approaches are most reliable.

Collaboration across disciplines is necessary for responsible AI in healthcare: The survey explicitly addresses its audience as "AI scientists, medical imaging researchers, and musculoskeletal clinicians," underscoring that safe, effective AI deployment in osteoporosis care requires ongoing dialogue between technical experts and clinical practitioners.
