振动反应成像系统在评估慢性阻塞性肺疾病患者生活质量及肺功能中的价值

目的 探讨振动反应成像系统(VRI)对慢性阻塞性肺疾病(COPD)患者生活质量及肺功能评估方面的作用.方法 选取在我院通过肺部呼吸VRI记录图像的住院患者76例,分析其图像特点,所得数据与患者应用呼吸问卷(st george's respiratory questionnaire, SGRQ)生活质量问卷(过去1年内的情况)得分及肺功能第1秒用力呼气容积(FEV1)进行相关分析.结果 COPDⅡ级患者VRI肺部定量数值(Quantitative Lung Data, QLD)与COPDⅢ级患者QLD分布差异无统计学意义.COPDⅡ级患者比COPD Ⅲ级患者最大能量图(maximal energy frame,MEF)最高值分数高,分别为(1.32±0.13)分vs(1.08±0.16)分(P<0.01).COPDⅡ级与COPD Ⅲ级患者比较其SGRQ值低,分别为(49±13)分vs(62±16)分(P<0.01).患者的MEF值与SGRQ值呈负相关(r=-0.932,P<0.01).结论 VRI中COPD Ⅱ级患者最大能量图值高于COPDⅢ级患者,患者MEF值与SGRQ值之间有相关性.VRI有助于对COPD患者肺功能评估,同时有助于协助评估COPD患者生活质量及预后.

Value of VRI on assessment of quality of life and lung function in patients with chronic obstructive pulmonary disease

Objective To explore the value of VRITM Vibration Response Imaging（VRI） system in assessment of quality of life and lung function in patients with chronic obstructive pulmonary disease（COPD）.Methods 76 subjects who had ever stayed in our hospital were selected and detected by VRI.Image characteristics of patients＇ VRI examination were recorded and analyzed.Correlation analysis was used among the data of VRI,scores of St George＇s Respiratory Questionnaire（SGRQ） and FEV1 of lung function test.Results There was not significant difference in distribution of Quantitative Lung Data（QLD） between moderate COPD（GOLD Ⅱ） and severe COPD（GOLD Ⅲ）.The maximum score of maximal energy frame（MEF） in moderate COPD was higher than severe COPD,（1.32±0.13） scores vs（1.08±0.16） scores（P〈0.01）.Scores of SGRQ in moderate COPD was lower than severe COPD,（49±13） scores vs（62±16） scores（P〈0.01）.It had negative correlation between the maximum scores of MEF and scores of SGRQ（r=0.932,P〈0.01）,the effect had statistical significance.Conclusion There was significant difference of the maximum score of MEF between moderate COPD（GOLD Ⅱ） and sever COPD（GOLD Ⅲ）.And there was negative correlation between the maximum score of MEF and the score of SGRQ.VRI contributes to assessing the lung function of patients with COPD.And it can also be used to assess the quality of life and prognosis in patients with COPD.
