目的探讨振动反应成像(VRI)在稳定期慢性阻塞性肺疾病(COPD)患者病情严重度分级中的应用价值。方法将2010年1月至6月南京医科大学附属南京第一医院呼吸科收治的210例COPD患者按病情严重度分为4级,对照组80名为健康志愿者,同时进行肺功能和VRI检查。结果 COPD组VRI结果与对照组相比差异有统计学意义(P<0.01)。振动曲线异常评分和动态图像异常评分随着COPD病情的严重程度显著增加(P<0.05)。结论 VRI在COPD病情严重程度分级中具有一定价值。
Objective To investigate the value of Vibration Response Imaging (VRI) in grading the severity of patients with stable chronic obstructive pulmonary disease (COPD). Methods A total of 210 COPD patients admitted to Department of Respiratory, Nanjing First Hospital, Nanjing Medical University from January to June 2010 were divided into four grades according to the severity of the disease and 80 healthy volunteers in the control group. Pulmonary function and VRI examination . Results The VRI results in COPD group were significantly different from those in control group (P <0.01). Vibration curve abnormality score and dynamic image abnormal score increased significantly with the severity of COPD (P <0.05). Conclusion VRI is of some value in the grading of COPD severity.
