Correlation of Computed Tomography thoracic cage ratio with pulmonary function tests in patients with chronic obstructive pulmonary disease.

Background: Chronic obstructive pulmonary disease is one of the leading causes of mortality in the world. The study was done to determine a correlation between CT thoracic cage ratio and pulmonary function tests in patients with COPD.


Method: A cross-sectional study was made involving 54 patients diagnosed with COPD using pulmonary function tests, who also underwent CT scan of the chest. It was conducted at the Philippine Heart Center using information gathered during the period January 2010 to December 2014. Included patients were age 40 years and above, diagnosed with COPD according to the Global Initiative for Chronic Obstructive Pulmonary Disease Guidelines, and underwent pulmonary function tests with chest CT scan with a maximum interval of one year.


Results: Using Pearson product moment of correlation, there was no significant correlation between thoracic cage ratio and pulmonary function test (FEV1/FVC) with r = 0.0779 for the thoracic cage ratio at the level of the carina and r = -0.1014 for the thoracic cage ratio 5 cm below the carina, where a p-value of 0.05 is considered significant.


Conclusion: There is no significant correlation between CT thoracic cage ratio and pulmonary function tests in patients with COPD.
