CORRELATION OF PFT & HRCT FOR THE EARLY DIAGNOSIS OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE IN A TERTIARY CARE CENTRE, INDORE

Abstract

Background & Methods: The aim of the study is to assess the usefulness of PFT & HRCT 
for early diagnosis of COPD. All the tests was perform with due permission from the 
Institutional Ethical Committee and informed consent from the subjects or their legal 
relatives. Subjects were included on the basis of their diagnosis of COPD as per GOLD 
guidelines. Unrelated causes of dyspnea other than COPD or its management like known 
cases of asthma, anemia, CHF, pulmonary embolism, ILD was excluded from the study. 
Results: The lower valve of sensitivity (33.98%) and specificity (22.22%) proves that PFT 
method is not very effective to identify the True positive and true negative cases. The 
proportion of false positive and false negative is very high which shows that actual positive 
and negative cases identified by HRCT method is quite high then those identified initially by 
PFT method.
