The SARS-Cov-2 pandemic took health care players across the world by surprise, including caregivers, managers and logisticians. In the absence of a vaccine or a specific therapy, detecting the disease at an early stage and isolating confirmed cases from the rest of the healthy population was soon considered to be essential. The RT-PCR technique was the gold standard method for testing for infection with the virus. It has high specificity but moderate sensitivity. It was difficult to access it during the first weeks of the pandemic. On the basis of the observations of the Chinese and Italian scientific community in particular, the recommendation was to combine use of the RT-PCR with a low-dose thoracic CT scan. In the absence of easy access to the RT-PCR, the use of the lung CT scan for a rapid triage of patients within emergency departments proved effective.
严重急性呼吸综合征冠状病毒2（SARS-CoV-2）大流行让世界各地的医疗保健从业者措手不及，其中包括护理人员、管理人员和后勤人员。在没有疫苗或特定疗法的情况下，尽早发现疾病并将确诊病例与其他健康人群隔离开来很快被认为至关重要。逆转录聚合酶链反应（RT-PCR）技术是检测病毒感染的金标准方法。它具有高特异性但中等灵敏度。在大流行的最初几周很难获得该检测。特别是根据中国和意大利科学界的观察结果，建议将RT-PCR与低剂量胸部CT扫描联合使用。在无法轻松获得RT-PCR检测的情况下，在急诊科使用肺部CT扫描对患者进行快速分诊被证明是有效的。
