Correlation analysis of chest HRCT quantitative parameters, exhaled nitric oxide, and pulmonary function in patients with chronic obstructive pulmonary disease

Key Points

• Quantitative parameters from HRCT correlate significantly with pulmonary function measurements in COPD, highlighting their diagnostic role.
• A key finding was that exhaled nitric oxide levels were linked to changes in pulmonary function, suggesting airway inflammation.
• Analysis was performed on patients with chronic obstructive pulmonary disease using chest HRCT and pulmonary function testing.
• The results may enhance the understanding of COPD pathology, but broader studies are needed for validation.
