An End-to-End Deep Learning Pipeline for Emphysema Quantification Using Multi-label Learning

Area of Science:

• Medical Imaging
• Artificial Intelligence
• Pulmonary Medicine

Background:

• Accurate diagnosis of lung pathologies like emphysema is crucial.
• Current methods for quantifying emphysema and generating differential diagnoses can be labor-intensive.
• Deep learning offers potential for automated analysis of medical images.

Purpose of the Study:

• To develop and validate an end-to-end deep learning pipeline for lung pathology differential diagnosis.
• To quantify the extent and distribution of emphysema in chest CT images.
• To classify five key lung tissue patterns: ground glass, fibrosis, micronodules, normal lung, and emphysematous lung.

Main Methods:

• Utilized a 3D Convolutional Neural Network (CNN) for volumetric lung segmentation.
• Employed a multi-label learning model for differential diagnoses and emphysema classification.
• Correlated AI-diagnosed emphysema with radiologist assessments.
• Validated the pipeline on two public datasets.

Main Results:

• The pipeline successfully performs end-to-end differential diagnosis of lung diseases.
• It accurately quantifies emphysema extent and distribution.
• Demonstrated competitive performance on publicly available chest CT datasets.

Conclusions:

• This is the first end-to-end deep learning pipeline for lung disease differential diagnosis and emphysema quantification.
• The proposed AI tool shows promise for improving the efficiency and accuracy of pulmonary diagnostics.
• Further validation on diverse datasets will enhance clinical applicability.
