Abstract

Chronic Obstructive Lung Disease, commonly known as COPD is defined by the Global Initiative for Chronic Disease as a preventable and treatable disease which is triggered by noxious particles and gas that is inhaled causing persistent airflow limitation. COPD was classified by GOLD according to its severity of airflow limitation as measured by post-bronchodilator FEV1 using a spirometer.


The objective of this study was to determine the correlation between the selected chest x-ray parameters (Lung width ratios) with the degree of chronic obstructive pulmonary disease as measured by PFT.


The retrospective study among 100 patients diagnosed with COPD (by PFT) with their corresponding chest xray and pulmonary function test results of patients diagnosed with COPD were reviewed and collated. Results showed significant correlation between the selected chest x-ray parameters (Upper Third to Lower Third Width Ratio) and the pulmonary function test among patients with COPD with the computed Pearson correlation between the computed lung width ratio and PFT which is


 


The use of radiographic lung width ratios is a good predictive index, through the aid of spirometry to correlate the degree of functional impairment for its severity. However, chest x-ray results may be used for rapid screening method when incentive spirometry is not readily available.
