HRCT对肺小气道病变的诊断价值分析

The Diagnostic Value of HRCT in Small Airways Disease of Lung Disease

目的 探讨高分辨率CT（HRCT））对肺小气道病变的诊断价值。方法 以2014年8月至2015年8月间于我院拟诊断为小气道病变的118例患者作为研究对象,所有患者同时进行了HRCT检查、胸部X线片、螺旋CT检查,比较三种检查方式对小气道病变征象（细支气管壁增厚、马赛克征、树芽征、空气潴留征等）的检出数量。结果 HRCT在小气道病变征象上检出的数量最多,与螺旋CT和胸部X线片检查检出的数量相比差异有统计学意义（χ^2=5.823、χ^2=3.846,P〈0.05,P〈0.05）。结论 HRCT是一种极好的影像学检查方式,应用于肺小气道病变的检查,对细支气管壁增厚、马赛克征、树芽征、空气潴留征等小气道病变征象能很好的显示,利于病变的诊断,临床值得推广运用。

Objective To investigate the diagnostic value of HRCT in the diagnosis of small airway disease. Methods From August 2014 to August 2015 in our hospital to be diagnosed as small airway lesions of 118 patients as research data, all patients with HRCT examination, chest X-ray, spiral CT examination, compared the three kinds of inspection for small airway disease signs （ small wall thickness, mosaic sign, tree bud sign, air retention sign, etc） . Results The number of HRCT in the small airway lesions was the most, and the number of CT and chest X-ray film examination was statistically significant （χ^2=5. 823、χ^2=3. 846,P〈0. 05）. Conclusion HRCT is an excellent imaging examination method, which is used in the diagnosis of small airway diseases such as small airway diseases, such as thin wall thickening, mosaic sign, tree bud sign, air retention sign and so on.
