Coronavirus disease (COVID-19), caused by a highly contagious novel coronavirus, has seen a rapid surge of cases over the past 6 months spreading to more than 215 countries and posing a global threat to mankind. Reverse transcriptase-polymerase chain reaction (RT-PCR) from pharyngeal swabs is considered the gold standard for diagnosis of this disease. Portable chest radiography (CXR), point of care ultrasound, and computed tomography (CT) are crucial modalities in diagnosis and follow-up. Portable CXR can help in patients who are clinically unstable, and also to prevent the cumbersome process of steriliastion after every CT scan. However, chest CT is useful as a problem-solving tool, to look for progression and complications associated with the disease. In a few cases, in our experience (as has also been documented by others), RT-PCR was negative in early disease, and CT chest was able to detect the radiologi-cal findings raising suspicion of COVID-19. With this pictorial review, we aim to describe and illustrate the typical, and a few atypical, radiological findings of this disease.
冠状病毒病（COVID-19）由一种具有高度传染性的新型冠状病毒引起，在过去6个月中病例迅速激增，已蔓延至215多个国家，对人类构成全球威胁。咽拭子逆转录聚合酶链反应（RT-PCR）被认为是诊断该疾病的金标准。便携式胸部X线摄影（CXR）、床旁超声和计算机断层扫描（CT）是诊断和随访的关键手段。便携式CXR对临床不稳定的患者有帮助，也可避免每次CT扫描后繁琐的消毒过程。然而，胸部CT作为一种解决问题的工具，有助于观察疾病的进展和并发症。根据我们的经验（其他人也有记录），在少数病例中，疾病早期RT-PCR呈阴性，但胸部CT能够检测到引起COVID-19怀疑的影像学表现。通过本图像综述，我们旨在描述和展示该疾病的典型及一些非典型影像学表现。
