Interstitial lung disease (ILD) is one of the most serious pulmonary complications associated with connective tissue diseases (CTDs), resulting in significant morbidity and mortality. Recently, lung ultrasound examination has appeared as a useful, feasible, non-invasive, radiation-free imaging technique with high sensitivity and specificity for the diagnosis of CTD-associated ILD. In this review, we discuss the literature concerning lung ultrasound findings (B-lines and pleural irregularities) in systemic sclerosis. We also examine the possible utility and potential limitations of lung ultrasound in other CTDs including: inflammatory myopathies, mixed connective tissue disease, and Sjögren's syndrome. Specifically, we compare the diagnostic accuracy of lung ultrasound with traditional imaging techniques and pulmonary functional tests.
间质性肺病（ILD）是与结缔组织疾病（CTD）相关的最严重的肺部并发症之一，导致发病率和死亡率显著增加。最近，肺部超声检查作为一种有用、可行、无创、无辐射的成像技术，具有很高的敏感性和特异性，可用于诊断 CTD 相关的 ILD。在这篇综述中，我们讨论了系统性硬化症中有关肺部超声表现（B 线和胸膜不规则）的文献。我们还研究了肺部超声在其他 CTD 中的可能应用和潜在局限性，包括：炎性肌病、混合性结缔组织病和干燥综合征。具体来说，我们比较了肺部超声与传统影像学技术和肺功能测试的诊断准确性。
