振动反应成像肺部定量数值在支气管哮喘中的临床应用
Clinical Application of Quantitative Lung Data of Vibration Response Imaging in Patients with Bronchial Asthma
摘要
Abstract
Objective To explore the value of quantitative lung data (QLD) of vibration response imaging (VRI) in diagnosis of bronchial asthma. Methods The QLD and VRI examinations of 90 patients with bronchial asthma (group A) and 90 healthy volunteers (group B) were performed. The QLD and abnormity and improvement of QLD were analyzed. Results There was no statistical significance in abnormity of QLD in areas before and after bronchial relaxation test between group A and group B (P >0.05). There was statistical significance in the total abnormity of QLD before and after bronchial relaxation test in group A (P <0.01), and the total abnormity of QLD before bronchial relaxation test between group A and group B (P <0.01). Improved amount of QLD in group A before and after bronchial relaxation test was 7.6 ?.2, and 95% confidence region was 6.4 ~8.3. There was a linear relationship in group A before and after bronchial relaxation test between the improved amount of QLD and FEV, (r =0.614, P <0.01), and also there was a significant relationship with improvement rate of FEV, (r =0.691, P <0.01). Conclusion The QLD of VRI is of some value performs a promising method in diagnosis of patients with bronchial asthma.关键词
