AJR:新型冠状病毒(Covid-19)成像功能与SARS和MERS重叠

虽然2019年新型冠状病毒疾病的成像特征(Covid-19)是可变的和非特异性的,但迄今为止报告的调查结果表明,严重急性呼吸综合征(SARS)和中东呼吸综合征(MERS)的调查结果表现出“显着重叠”。到了一个前进的文章美国x射线学杂志(AJR.)。
COVID-19 is diagnosed on the presence of pneumonia symptoms (e.g., dry cough, fatigue, myalgia, fever, dyspnea), as well as recent travel to China or known exposure, and chest imaging plays a vital role in both assessment of disease extent and follow-up.
根据加州大学洛杉矶分校的Melina Hosseiny对目前有关COVID-19的临床文献的回顾,她总结道:“早期证据表明,至少85%的患者初始胸部显像将显示异常,其中75%的患者最初双侧肺受累,最常表现为胸膜下和周围区毛玻璃样混浊和实变。”
此外,“较旧的年龄和渐进式巩固”可能意味着整体预后较差。
不同于SARS和mers(最初的胸部成像异常通常是单侧的),covid -19在最初的成像中更有可能累及双肺。
“据我们所知,”Hosseiny等人继续说道,胸腔积液未见COVID-19患者出现空化、肺结节和淋巴结病变的报道。”
最终,这篇AJR文章的作者推荐了从Covid-19恢复的患者的后续随访,以评估长期甚至永久性肺部损伤,包括纤维化 - 如SARS和MERS感染所示。
