PURPOSE OF REVIEW
This review aims to explore the different imaging modalities, such as chest radiography (CXR), computed tomography (CT), ultrasound, PET/CT scan, and MRI to describe the main features for the evaluation of the chest in COVID-19 patients with ARDS.
RECENT FINDINGS
This article includes a systematic literature search, evidencing the different chest imaging modalities used in patients with ARDS from COVID-19. Literature evidences different possible approaches going from the conventional CXR and CT to the LUS, MRI, and PET/CT.
SUMMARY
CT is the technique with higher sensitivity and definition for studying chest in COVID-19 patients. LUS or bedside CXR are critical in patients requiring close and repeated monitoring. Moreover, LUS and CXR reduce the radiation burden and the risk of infection compared with CT. PET/CT and MRI, especially in ARDS patients, are not usually used for diagnostic or follow-up purposes.
目的综述
本文旨在探讨不同的影像学模式，如胸部 X 线摄影（CXR）、计算机断层扫描（CT）、超声、PET/CT 扫描和 MRI，以描述用于评估 COVID-19 合并急性呼吸窘迫综合征（ARDS）患者胸部的主要特征。
最近的发现
本文包括一项系统文献检索，证明了在 COVID-19 合并 ARDS 患者中使用的不同胸部影像学模式。文献证据表明，从常规 CXR 和 CT 到 LUS、MRI 和 PET/CT，可能有不同的方法。
总结
CT 是研究 COVID-19 患者胸部的一种具有较高灵敏度和清晰度的技术。在需要密切和重复监测的患者中，LUS 或床边 CXR 至关重要。此外，与 CT 相比，LUS 和 CXR 降低了辐射负担和感染风险。在 ARDS 患者中，PET/CT 和 MRI 通常不用于诊断或随访目的。
