Deep learning model for identification of metabolic bone disease of prematurity using wrist radiographs
Explore the groundbreaking AI advancements in medical diagnostics, offering enhanced accuracy and efficiency for critical early interventions.
Executive Impact: Pioneering AI in Neonatal Healthcare
This study developed a deep learning model using wrist radiographs to identify metabolic bone disease (MBD) of prematurity. The DenseNet-based model achieved high performance with an AUROC of 0.961 internally and 0.927 externally. Crucially, it significantly improved diagnostic accuracy for non-radiologists (65.4% to 78.7%), facilitating timely diagnosis and treatment.

Advanced Model Accuracy in MBD Detection
The study deployed seven deep learning algorithms, with DenseNet-121 demonstrating the highest performance. For the internal dataset, DenseNet-121 achieved an AUROC of 0.961, sensitivity of 94.4%, specificity of 91.2%, and an overall accuracy of 92.0%. In the external validation study, the model maintained robust performance with an AUROC of 0.927, indicating strong generalizability across different clinical settings.
This performance underscores the model's capability in accurately identifying radiographic features of Metabolic Bone Disease (MBD) of prematurity, making it a powerful diagnostic aid.
Transforming Clinical Decision Support
The developed AI model significantly improved diagnostic performance, particularly for non-radiologists. In the reader study using the external dataset, pediatricians' accuracy increased from 65.4% to 78.7% (P = 0.008) when assisted by the AI. Radiologists also showed improvement, though not statistically significant. The model helped correct 51.6% of false positives and 65.5% of false negatives internally, demonstrating its utility in mitigating both overdiagnosis and missed diagnoses.
This indicates the AI's potential to facilitate timely diagnosis and treatment of MBD, reducing disease progression and improving patient outcomes.
Rigorous Development & Validation
The study employed a rigorous methodology, including internal (Seoul National University Hospital) and external (Seoul National University Bundang Hospital) datasets for development and validation. A precise Region of Interest (ROI) selection, focusing on the radius metaphysis, ensured the model learned from clinically relevant anatomical regions. Extensive data augmentation was used during training, including rotation, brightness, contrast, and noise, to enhance the model's robustness to real-world imaging variations in NICU settings.
The use of ImageNet-pretrained models as baselines for seven different algorithms further solidified the methodological approach.

Real-World Impact: Enhancing MBD Diagnosis in Preterm Infants
Metabolic Bone Disease (MBD) of prematurity is a significant complication, and its early detection is crucial. The developed deep learning model serves as a vital tool to assist clinicians, particularly non-radiologists, in identifying radiographic signs suggestive of MBD more accurately and conveniently. This AI intervention can significantly accelerate timely treatment and prevent disease progression in a vulnerable patient population.
Beyond high-resource settings, the model holds immense promise for improving healthcare in regions with limited access to specialized radiological expertise. Its integration into clinical decision support systems (CDSS) or mobile applications could democratize advanced diagnostic capabilities, ensuring better outcomes globally.
