Enhanced Differentiation of Pneumonic-Type Lung Cancer and Inflammatory Pneumonia Through Quantitative Peri-Lesional Densitometry Mapping Using Thin-Slice Volume Rendering
To develop and validate a diagnostic model integrating densitometry-derived thresholds into modified thin-slab volume rendering (tsVR) for differentiating pneumonic-type lung cancer (PTLC) from inflammatory pneumonia.
Key Findings:
The tsVR model outperformed conventional CT feature-based diagnosis with internal validation AUC of 0.86 and external validation AUC of 0.81.
Sensitivity of the tsVR model was 90% in both internal and external validations.
Good inter-observer agreement was noted with a kappa value of 0.713.
Interpretation:
The tsVR approach significantly enhances the differentiation of PTLC from inflammatory pneumonia, demonstrating robust diagnostic performance across various conditions.
Limitations:
The study is retrospective and may be subject to selection bias.
Generalizability may be limited to specific imaging protocols and scanner types used in the study.
Conclusion:
The modified tsVR model provides a clinically applicable and stable method for improving diagnostic accuracy in distinguishing PTLC from inflammatory pneumonia.
