Objectives: In this study we aimed to investigate the
relationship between expiratory HRCT findings, tracheal
index (TI) and pulmonary function tests in patients with
chronic obstructive pulmonary disease (COPD).
Materials and methods: Sixty patients diagnosed with
COPD in our hospital, department of pulmonary medicine,
and 65 subjects complaining of cough with normal pulmonary
function tests as a control group were enrolled in
the study. All subjects were evaluated with HRCT. HRCT
and pulmonary function tests were performed in same
day and FEV1, FVC, FEV1/FVC values were recorded.
Pearson Chi-Square, Independent Samples T test, and
Mann Whitney U test were used for statistical evaluation.
Results: Subjects’ mean age was 55.44±10.22 years.
Bronchiectasis, bronchial wall thickening, emphysema,
centrilobular bronchiolar thickening and air trapping were
significantly higher in COPD group than control group. In
patient group, TI values were lower than control group (p
< 0.001). Also there was moderate negative relationship
between TI and age (p = 0.00, r = -0.48).
Conclusions: Expiratory HRCT findings and TI values
show various degrees of relationship with pulmonary
function test results in patients with COPD. Despite normal
pulmonary function tests, pathological changes can
be detected in expiratory HRCT scans.
