【摘要】:目的探讨肺部振动反应成像(VRI)肺部定量数据(QLD)的异常度和波动度在气流受限疾病诊断中的应用价值。方法对168例因肺部疾病导致气流受限的住院患者和116例健康志愿者行VRI检查,并进行比较分析。结果慢性阻塞性肺疾病(COPD)患者和哮喘患者的异常度及波动度均明显高于健康志愿者,差异有统计学意义(均P0.05)。若以异常度≥20.0或波动度≥5.0为正常界值,则健康志愿者检出率为85.90%,COPD患者检出率为83.95%,哮喘患者检出率为82.76%。支气管舒张试验前后COPD患者的QLD异常度和波动度均变化不明显,差异无统计学意义(均P0.05)。舒张试验后哮喘患者QLD异常度显著降低,差异有统计学意义(P0.05),但波动度无显著变化,差异无统计学意义(P0.05)。结论 VRI作为一种新的检查手段在气流受限疾病中有特异性表现,通过公式将QLD转换为异常度和波动度两项指标后,可有助于气流受限性疾病的诊断。
[Abstract]:Objective to evaluate the value of QLDs in the diagnosis of airflow confined diseases by pulmonary vibration response imaging (VRI) pulmonary quantitative data (QLDD). Methods VRI was performed in 168 inpatients with airflow limitation due to pulmonary diseases and 116 healthy volunteers. Results the abnormal degree and fluctuation degree in patients with chronic obstructive pulmonary disease (COPD) and asthma were significantly higher than those in healthy volunteers (P 0.05). If abnormal degree 鈮,
