Artificial intelligence combined with computed tomography or X-ray radiography: Potential solution for opportunistic screening for osteoporosis
Osteoporosis and osteoporotic fractures are a growing global health concern, exacerbated by aging populations. Current gold-standard screening methods like DXA are limited by cost, accessibility, and awareness. This analysis explores the significant potential of AI integrated with radiology (CT, X-ray) for opportunistic screening, offering a low-cost, easy-to-use, and accessible solution. While AI shows promising accuracy (e.g., AUC up to 0.9987), clinical implementation faces challenges including algorithm precision, financial investment, managing incidental findings, and complex ethical considerations like data privacy and bias. A robust collaborative framework is essential for successful integration, balancing innovation with patient safety and equitable access.

Overview of Osteoporosis
Osteoporosis is a systemic bone disease leading to decreased bone mass and microstructural changes, increasing fracture risk. It disproportionately affects women but is also prevalent in aging men. Globally, it causes over 9 million fractures annually, with hip fractures being particularly problematic due to high mortality (20-30% within a year) and disability (50%). The economic burden is substantial, with direct costs for treating osteoporotic fractures estimated between $500-650 billion annually in Canada, Europe, and the United States.
Current Screening Status
Primary prevention through screening is crucial for early intervention. WHO recommends screening for individuals over 65, or 50-64 with clinical risk factors. DXA is the gold standard but has low screening rates due to high cost, limited accessibility, and lack of awareness among patients and physicians. Existing clinical risk-scoring tools (SCORE, OSIRIS, FRAX) also have limitations in sensitivity, specificity, and general applicability across diverse populations.

Highest Reported AUC for AI-based Osteoporosis Screening (Lee et al., 2019)
AI's rapid development, particularly in deep learning and convolutional neural networks, offers new opportunities for opportunistic osteoporosis screening. By integrating AI with routine radiographic images (CT, X-ray), it enables early detection and diagnosis without additional cost or radiation. Studies have demonstrated remarkable efficacy, with AI models achieving high diagnostic accuracy and AUC values, transforming how osteoporosis is identified and managed on a large scale.

Clinical Review & Patient Management
This flowchart outlines the streamlined process of using AI for opportunistic osteoporosis screening. Leveraging existing imaging data, AI algorithms can efficiently analyze bone structure and density, generating automated reports for clinical review and subsequent patient management, significantly improving early detection pathways.
AI vs. Traditional DXA
| Feature | Traditional DXA | AI-based Opportunistic Screening (Radiography) |
|---|---|---|
| Cost | High (Specialized Equipment) | Low (Leverages existing images) |
| Accessibility | Limited (Large hospitals, specialized staff) | High (Any clinic with radiography) |
| Radiation Exposure | Low (Targeted DXA) | Low (Existing images, no additional exposure) |
| Diagnostic Focus | Gold standard for BMD diagnosis | Opportunistic screening/risk assessment |
| Primary Use | Confirmation of osteoporosis | Early detection, triage for DXA |
While DXA remains the gold standard for osteoporosis diagnosis, AI-based opportunistic screening offers distinct advantages in cost, accessibility, and leveraging existing data. It serves as an excellent pre-screening or risk assessment tool to identify high-risk individuals who may benefit from further DXA evaluation.
Challenges to Implementation
Implementing AI-driven opportunistic screening faces several hurdles: ensuring clinical precision and reliability of AI algorithms in real-world settings, addressing substantial financial investments for AI integration (technology acquisition, staff training, system compatibility), and managing the increased workload from incidental findings. A standardized protocol for managing incidental findings is crucial to prevent unnecessary testing and overtreatment.
Ethical Considerations
Addressing Bias in AI for Osteoporosis Screening
Challenge: AI models trained on imbalanced datasets can exhibit racial or demographic bias, leading to inaccurate predictions for vulnerable populations. The article highlights that existing tools have historically focused on female populations, potentially underrepresenting male-specific risks.
Impact: Misdiagnosis or delayed diagnosis in underrepresented groups, exacerbating health inequalities and eroding trust in AI systems. The US healthcare system has revealed racial bias in AI outcomes (Obermeyer et al., 2019).
Solution: Develop robust, diverse, and representative training datasets. Implement rigorous external validation across varied populations. Ensure algorithmic transparency and interpretability ('explainable AI'). Establish clear accountability frameworks for AI-driven medical decisions.
