Purpose: To assess the change in Tracheal index in patients of COPD as a function of severity and its correlation with PFT parameters. Methods: HRCT scans of 48 patients were done and correlated with Pulmonary Function Tests taken within 2 weeks of the study. We obtained TI by dividing the coronal diameter of the trachea by sagittal diameter and multiplying it by 100 at a level 2 cm above the aortic arch. These values were then correlated with COPD severity based on PFT results. Results: The mean tracheal index in our study was 0.672 ± 0.10. The mean tracheal index in mild emphysema group was 0.73 ± 0.07 and in the moderate to severe group 0.61 ± 0.08. A significant correlation was found between tracheal index and PFT parameters signifying COPD severity i.e. FEV1, FEV1/FVC, RV/TLC and Pef 25%-7.. Read More»
