【摘要】:目的探討肺部振動(dòng)反應(yīng)成像(VRI)肺部定量數(shù)據(jù)(QLD)的異常度和波動(dòng)度在氣流受限疾病診斷中的應(yīng)用價(jià)值。方法對(duì)168例因肺部疾病導(dǎo)致氣流受限的住院患者和116例健康志愿者行VRI檢查,并進(jìn)行比較分析。結(jié)果慢性阻塞性肺疾病(COPD)患者和哮喘患者的異常度及波動(dòng)度均明顯高于健康志愿者,差異有統(tǒng)計(jì)學(xué)意義(均P0.05)。若以異常度≥20.0或波動(dòng)度≥5.0為正常界值,則健康志愿者檢出率為85.90%,COPD患者檢出率為83.95%,哮喘患者檢出率為82.76%。支氣管舒張?jiān)囼?yàn)前后COPD患者的QLD異常度和波動(dòng)度均變化不明顯,差異無統(tǒng)計(jì)學(xué)意義(均P0.05)。舒張?jiān)囼?yàn)后哮喘患者QLD異常度顯著降低,差異有統(tǒng)計(jì)學(xué)意義(P0.05),但波動(dòng)度無顯著變化,差異無統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論 VRI作為一種新的檢查手段在氣流受限疾病中有特異性表現(xiàn),通過公式將QLD轉(zhuǎn)換為異常度和波動(dòng)度兩項(xiàng)指標(biāo)后,可有助于氣流受限性疾病的診斷。
[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,
