The accuracy of chest radiograph in detecting bronchiectasis with high resolution computed tomography as reference standard.


Background: Chest radiography is the most readily available imaging modality in evaluating patients suspected with bronchiectasis. The aim of the study was to determine the accuracy of chest radiographs in detecting bronchiectasis using high resolution computed tomography (HRCT) as reference standard.


Methods: This is a criterion based ross-sectional study. We compared the chest radiographs of 45 patients suspected with bronchiectasis with HRCT findings (using the criteria of Gudjberg and Naidich). We determined the sensitivity, specificity, positive predictive value and negative predictive value of chest radiographs in the detection of bronchiectasis. We also determined inter- and intraobserver variability determined.


Results: The sensitivity of chest radiographs to detect bronchiectasis was 84% with a specificity of 64%. The positive predictive value was 65% while the negative predictive value was 84%.


 Conclusion: Chest radiographs ca help out rule out the presence of bronchiectasis. A negative chest radiograph finding is a good indicator of the absence of bronchiectasis.
