重度吸烟者肺部振动反应成像动态图像特征初探

目的 探讨肺功能正常重度吸烟者的振动反应成像(vibration vesponse vmaging,VRI)动态图像特征.方法 观察60例健康非吸烟者(对照组)和67例肺功能正常的重度吸烟者(重度吸烟组)VRI图像.首先采集两组受试者的临床资料(病史、体格检查、胸部X线),然后进行肺功能测定和VRI检查,比较两组之间V...

Study on the characteristics of vibration response imaging among heavy smokers whose pulmonary function is normal

Objective Vibration response imaging(VRI) is a new lung sound imaging technology.The study was preliminarily to explore the image properties of heavy smokers. Methods All subjects were divided into two groups heavy smokers whose pulmonary function was normal, healthy non-smokers.First of all, we asked their case history and did physical examination. Then we tested their lung function and checked up their chest X-ray and VRI. Finally,the different of VRI dynamic imaging between the two groups were analyzed. Results dynamic imaging in heavy smokers group which appeared disorder, skip,derangement,delay were separately accounted for 16.4% ,64. 2% , 16.4% , 9. 0%. While in healthy nonsmokers group respectively account for 6. 7, 3. 3% , 0. 0% , 0. 0%. The results between heavy smokers whose pulmonary function is normal and healthy non-smokers were significantly different. Conclusions The dynamic image of the VRI heavy smokers whose pulmonary function was different from healthy nonsmokers group.
