Abstract：
UNASSIGNED: Severe acute respiratory syndrome - coronavirus 2 (SARS-CoV-2) is a single-stranded positive ribonucleic acid virus of the coronaviridae family. The disease caused by this virus has been named by the World Health Organization coronavirus disease 19 (COVID-19), whose main manifestation is interstitial pneumonia. Aim of this study is to describe the radiological features of SARS-CoV-2 infection in its original form, to correlate the high-resolution computed tomography (HRCT) patterns with clinical findings, prognosis and mortality, and to establish the need for treatment and admission to the intensive care unit.
UNASSIGNED: From March 2020 to May 2020, 193 patients (72 F and 121 M) who were swab positive for SARS-CoV-2 were retrospectively selected for our study. These patients underwent HRCT in the clinical suspicion of SARS-CoV-2 interstitial pneumonia.
UNASSIGNED: Our results confirm the role of radiology and, in particular, of chest HRCT as a technique with high sensitivity in the recognition of the most peculiar features of COVID-19 pneumonia, in the evaluation of severity of the disease, in the correct interpretation of temporal changes of the radiological picture during the follow-up until the resolution, and in obtaining prognostic information, also to direct the treatment.
UNASSIGNED: Chest computed tomography cannot be considered as a substitute for real-time - polymerase chain reaction in the diagnosis of COVID-19, but rather supplementary to it in the diagnostic process as it can detect parenchymal changes at an early stage and even before the positive swab, at least for patients who have been symptomatic for more than 3 days.

摘要：
■严重急性呼吸道综合征-冠状病毒2（SARS-CoV-2）是冠状病毒科的单链正核糖核酸病毒。由该病毒引起的疾病已被世界卫生组织冠状病毒19（COVID-19）命名，主要表现为间质性肺炎。这项研究的目的是描述SARS-CoV-2感染的放射学特征，将高分辨率计算机断层扫描（HRCT）模式与临床发现相关联，预后和死亡率，并确定需要治疗和入住重症监护室。
■从2020年3月至2020年5月，回顾性选择了193名SARS-CoV-2拭子阳性的患者（72F和121M）进行我们的研究。这些患者在临床怀疑SARS-CoV-2间质性肺炎时接受了HRCT检查。
■我们的结果证实了放射学的作用，特别是,胸部HRCT作为识别COVID-19肺炎最特殊特征的高灵敏度技术，在评估疾病的严重程度时，在随访期间对放射学图像的时间变化的正确解释，直到分辨率，在获得预后信息方面，也指导治疗。
在COVID-19的诊断中，胸部计算机断层扫描不能被视为实时聚合酶链反应的替代品，而是在诊断过程中的补充，因为它可以在早期甚至在阳性拭子之前检测到实质变化，至少对于症状超过3天的患者。
