| Purpose To describe high-resolution computed tomography ( HRCT) findings of asthma and compare those
findings with chest plain films. Methods 28 asthmatic patients (9M ,19F ;age :20～75 years ,M = 37. 5) who had undergone both HRCT of lungs and chest plain films were evaluated. HRCT was performed with a thin-section (1～1. 5 mm collimation) technique and a high-freguency reconstruction algorithm. In all subjects ,end-inspiratory scans were obtained and 7
patients were also performed with end2expiratory scans. The images were obtained at window levels of-670～-700 Hu
and at a window width of 1500 Hu. Results On chest plain films ,4 cases showed lung volume increasing and pulmonary
parenchymal transparency increasing(14. 3 %) ,predominant lung marking in 5 cases ,mediastinal emphysema in one case.
The positivity of chest plain films was 25 %. Of these 28 patients with HRCT scans showed bronchial wall thickening in 15
cases(53. 6 %) ,bronchiectasis in 6 cases (21. 4 %) ,mosaic pattern in 3 cases (11. 8 %) ,mediastinal emphysema in one case
and central lobular emphysema in 4 cases ,air trapping on end-expiratory CT scans in 5 cases. The positivity of HRCT scans
was 71. 4 %. Conclusion HRCT may be useful for evaluating pulmonary abnormality of patients with asthma and more
valuable than chest plain films. |
