摘要
目的探讨结缔组织病相关性间质性肺疾病超声与HRCT的相关性。方法选取我院风湿免疫科明确诊断为结缔组织病的患者70例,分别行肺超声及HRCT获得B线、Warrick评分并进行相关性分析,对两种评分进行分级,并对分级结果进行一致性分析。结果 LUS的灵敏度、特异度、阳性似然比和阴性似然比分别为82%、80%、4.1、0.225。Spearman相关分析表明,肺超声评分及HRCT评分在P=0.05水平呈强烈正相关(r=0.870,P<0.001),两种分级结果一致性Kappa值为0.598。结论结缔组织病相关性间质性肺疾病超声与HRCT具有良好的相关性,肺超声可以作为一种诊断及评估结缔组织病相关性间质性肺疾病的新型影像学方法。
Objective To investigate the correlation between lung ultrasound(LUS)and HRCT of connective tissue disease associated interstitial lung disease(CTD-ILD).Methods 70 patients with CTD were selected in the department of rheumatology of our hospital.All subjects underwent HRCT followed by lung ultrasound,we obtained and graded B line score and Warrick score.The correlation between two scores and the consistency of two grades were analysed.Results The sensitivity,specificity,positive and negative predictive value of LUS was 82%,80%,4.1,0.225.A significantly positive correlation between LUS score and HRCT score(r=0.870,P<0.001)was found.Kappa values for two grades was 0.598.Conclusions There is a significantly positive correlation between LUS and HRCT in CTD-ILD.LUS could be a new imaging method for diagnosis and evaluation of CTD-ILD.
