A machine learning model based on chest CT images accurately diagnoses and grades the severity of COPD.
Key Details
- 1Researchers developed a machine learning model using chest CT data from 173 COPD patients and 176 healthy controls.
- 2The model segments the lung parenchyma, airway, pulmonary artery, and vein, then extracts imaging features.
- 3Diagnostic accuracy for COPD was 95% (training set) and 96% (test set); AUC was 0.98 and 0.97, respectively.
- 4Severity grading accuracy was 78% (training) and 72% (test); AUC was 0.89 and 0.8.
- 5Traditional spirometry tests may be less effective or difficult for some patients, highlighting CT's added value.
