Abstract：
Lung involvement represents a fearful complication in rheumatoid arthritis (RA), potentially involving all compartments of the pulmonary system. Regarding interstitial lung disease (ILD), the HRCT represents the gold standard technique for its diagnosis; however, the examination is burdened by radiation exposure and high costs. In addition, although some risk factors for ILD are known, no algorithms exist to know which patients to submit to HRCT and when. In this context, lung ultrasound (LUS) showed promising results for at least 10 years, demonstrating correlation with high resolution computed tomography (HRCT) findings in other rheumatic diseases. Here, LUS may represent a screening test providing additional information to clinical examination and pulmonary function tests. The data deriving from LUS experience in other rheumatic diseases could steer the future towards the use of this technique also in RA patients, and in this review, we report the most relevant literature regarding LUS in RA-ILD.
摘要：
肺部受累代表类风湿性关节炎（RA）的可怕并发症，可能涉及肺系统的所有隔室。关于间质性肺病（ILD），HRCT代表了其诊断的黄金标准技术；然而，检查受到辐射暴露和高成本的负担。此外,虽然ILD的一些危险因素是已知的，不存在算法来知道哪些患者接受HRCT以及何时接受HRCT.在这种情况下，肺超声（LUS）在至少10年内显示出有希望的结果，与其他风湿性疾病的高分辨率计算机断层扫描（HRCT）发现相关。这里,LUS可以代表为临床检查和肺功能测试提供额外信息的筛查测试。从LUS在其他风湿性疾病中的经验得出的数据可以引导将来在RA患者中也使用该技术，在这次审查中，我们报告了有关RA-ILD中LUS的最相关文献。
