多层螺旋CT肺功能成像技术在慢性阻塞性肺部疾病中的应用研究

Application of multislice CT pulmonary functional imaging technology in chronic obstructive pulmonary disease

摘要:

对慢性阻塞性肺部疾病（chronic obstructive pulmonary disease，COPD）患者气道病变的多层螺旋 CT（multislice comput－ed tomography，MSCT）肺功能成像与肺功能检查（pulmonary function test，PFT）结果的关系及应用进行综述。首先对 COPD 患者气道病变及其发病原因进行了阐述，然后对传统气道病变评价方法（PFT）的局限性进行了分析，在此基础上对 MSCT 的功能及其优点进行了评价，通过参考其他学者的研究结果，对 MSCT肺功能成像技术和PFT结果的关系进行了综合分析，并认为 MSCT 的使用为定量评价 COPD 患者气道病变提供了有利的依据和有价值的信息。MSCT肺功能成像与肺功能表现具有明显的相关性，可较好地反映气道病变，是诊断COPD及评价肺功能水平有效的影像学工具。

Abstract:

In this study，application and relationship between multislice CT（MSCT） pulmonary functional imaging technology and pulmonary function test in patients with airway lesions were reviewed. First，airway lesions and its causes in patients with chronic ob－structive pulmonary disease（COPD） were elaborated. Then limitation of traditional evaluation method for airway lesion（pulmonary function test） was analyzed. On this basis，function and advantages of MSCT was evaluated. Comprehensive analysis was conducted on the relationship between results of MSCT pulmonary functional imaging technology and pulmonary function test by referring to findings of other scholars. Use of MSCT provides a favorable basis and valuable information for quantitative evaluation of patients with COPD airway lesions. MSCT pulmonary functional imaging technology has significant correlation with pulmonary function test and can reflect airway disease preferably. It is an effective imaging tool for diagnozing COPD and evaluating pulmonary functional level.
