Comparing Stacking Ensemble Techniques to Improve Musculoskeletal Fracture Image Classification.

Area of Science:

• Medical imaging analysis
• Artificial intelligence in healthcare
• Orthopedic diagnostics

Background:

• Bone fractures are a leading cause of emergency room visits, necessitating prompt and accurate diagnosis.
• X-ray interpretation for fractures requires specialized radiologists, whose availability can be limited.
• Accurate and rapid fracture detection is crucial to prevent long-term disability.

Purpose of the Study:

• To enhance the performance of Convolutional Neural Networks (CNNs) for bone fracture detection.
• To develop a more reliable and robust diagnostic tool for emergency room settings.
• To improve the accuracy of fracture diagnosis through ensemble machine learning techniques.

Main Methods:

• Utilized various Convolutional Neural Networks (CNNs) for image classification.
• Implemented a stacking ensemble technique to combine predictions from multiple CNNs.
• Evaluated the ensemble model's performance against individual CNN models.

Main Results:

• The stacking ensemble model demonstrated superior performance compared to individual CNNs.
• The ensemble approach achieved an average performance improvement of 10% over single models.
• The developed tool offers a reliable second opinion for emergency room physicians.

Conclusions:

• Ensemble techniques significantly boost the accuracy of AI-based fracture detection.
• This AI tool can support clinical decision-making in emergency departments.
• Improved fracture diagnosis through AI can lead to better patient outcomes and reduced disability.
