In December 2019, an outbreak of coronavirus infection emerged in Wuhan, Hubei Province of China, which is now named Coronavirus Disease 2019 (COVID-19). The outbreak spread rapidly within mainland China and globally. This paper reviews the different imaging modalities used in the diagnosis and treatment process of COVID-19, such as chest radiography, computerized tomography (CT) scan, ultrasound examination, and positron emission tomography (PET/CT) scan. A chest radiograph is not recommended as a first-line imaging modality for COVID-19 infection due to its lack of sensitivity, especially in the early stages of infection. Chest CT imaging is reported to be a more reliable, rapid, and practical method for diagnosis of COVID-19, and it can assess the severity of the disease and follow up the disease time course. Ultrasound, on the other hand, is portable and involves no radiation, and thus can be used in critically ill patients to assess cardiorespiratory function, guide mechanical ventilation, and identify the presence of deep venous thrombosis and secondary pulmonary thromboembolism. Supplementary information can be provided by PET/CT. In the absence of vaccines and treatments for COVID-19, prompt diagnosis and appropriate treatment are essential. Therefore, it is important to exploit the advantages of different imaging modalities in the fight against COVID-19.
2019 年 12 月，中国湖北省武汉市爆发了冠状病毒感染疫情，现称为 2019 年冠状病毒病（COVID-19）。疫情迅速在中国内地和全球蔓延。本文综述了 COVID-19 诊断和治疗过程中使用的不同影像学方法，如胸部 X 线摄影、计算机断层扫描（CT）、超声检查和正电子发射断层扫描（PET/CT）。由于胸部 X 线摄影的敏感性较差，尤其是在感染的早期阶段，因此不建议将其作为 COVID-19 感染的一线影像学方法。胸部 CT 成像被报道为诊断 COVID-19 的一种更可靠、快速和实用的方法，它可以评估疾病的严重程度并随访疾病的病程。另一方面，超声便携且无辐射，因此可用于危重症患者评估心肺功能、指导机械通气以及识别深静脉血栓和继发性肺血栓栓塞症。PET/CT 可以提供补充信息。在 COVID-19 没有疫苗和治疗方法的情况下，及时诊断和适当治疗至关重要。因此，在抗击 COVID-19 中利用不同影像学方法的优势非常重要。
