Utilizing Deep Learning to Distinguish Between Non-Tuberculous Mycobacterial Lung Disease and Pulmonary Tuberculosis via Chest CT Imaging
To develop and validate a deep learning model for the automatic differentiation of non-tuberculous mycobacterial lung disease (NTM-LD) and pulmonary tuberculosis (PTB) using chest CT imaging.
Key Findings:
3D ResNeXt model achieved an AUC of 0.89 and accuracy of 0.89 on the training set.
On the independent test set, the model achieved an AUC of 0.83 and accuracy of 0.84.
Statistical analysis confirmed the model's superiority over six comparator architectures (p < 0.05).
Grad-CAM visualizations indicated specific imaging features for NTM-LD and PTB.
Interpretation:
The 3D ResNeXt model demonstrates high accuracy and interpretability in differentiating NTM-LD from PTB, suggesting its potential as a clinical decision-support tool.
Limitations:
Retrospective design may introduce selection bias.
Validation in a multicenter prospective study is needed for broader applicability.
Conclusion:
The 3D ResNeXt model shows promise for clinical use in differentiating NTM-LD from PTB, pending further validation.
