Abstract :

Background: Quantitative computed tomography can effectively characterize and quantify the extent of emphysema and air trapping related to small airways disease.Here we highlight computed–tomography findings of COPD and correlation with spirometric values.Aim: To describe and analyse the morphology of lung on HRCT in patients with COPD and correlate the findings of MDCT by volumetric analysis and densitometry with pulmonary function tests and severity of the disease.Methods:The study group included a total of 86 adult patients of either sex with a clinical suspicion of COPD and those who undergone MDCT of thorax.Results:There was a preponderance of male patients with highly significant correlation between values of mean lung density and low attenuation values (r=–0.707, p<0.000I) .Linear regression curve analysis reveal (R²=0.445) 44.5 % of the patients to have strong linear correlation between values of mean lung density , LAV and spirometric values. Conclusion: The present study concludes that Multi detector computed tomography is an invaluable tool in defining and quantifying COPD and characterization of emphysematous changes
