Internal Test AUC (Ensemble Model)
Radiologists often face challenges in differentiating benign from malignant sacral bone lesions due to their similar imaging characteristics. This study aimed to develop an ensemble deep learning (DL) model that can preoperatively distinguish between benign and malignant sacral tumors using noncontrast computed tomography images. This metric showcases the high internal accuracy achieved by the model in distinguishing tumor types.

Diagnostic Evaluation (Internal/External)
An ensemble deep learning (DL) model was developed, integrating both 2D and 3D DenseNet121 architectures with human radiologist interpretation. The model underwent rigorous internal validation via fivefold cross-validation and external testing using data from multiple independent centers to ensure robust and generalizable performance.
| Model | Internal Test (AUC / F1 Score) | External Test (AUC / F1 Score) | Radiologist Improvement |
|---|---|---|---|
| 3D-DenseNet121 | 0.8871 / 0.8823 | 0.8099 / 0.8533 |
|
| Senior Radiologist (Manual) | 0.8574 / 0.8879 | 0.8553 / 0.8406 |
|
| Ensemble (3D-DL + Human) | 0.9139 / 0.9054 | 0.8713 / 0.8571 |
|
The ensemble model, integrating 3D-DenseNet121 with human interpretation, demonstrated the most robust performance, achieving high AUC and F1 scores on both internal and external test sets. All radiologists, particularly junior ones, experienced significant improvements in diagnostic performance when assisted by the AI model.
Enhanced Diagnostic Confidence for Sacral Tumors
The integration of the deep learning model, particularly the 3D-DenseNet121, with human interpretation significantly improved diagnostic accuracy for differentiating benign and malignant sacral bone tumors. This enhancement was most pronounced among junior radiologists, who saw considerable gains in AUC, accuracy, sensitivity, and specificity. By providing reliable decision support, the model can help to reduce unnecessary biopsies, alleviate patient anxiety, and guide appropriate management for sacral tumor patients, ultimately leading to more efficient clinical workflows and improved patient outcomes. This reduces the dependency on contrast imaging and MRI in musculoskeletal oncology.
