BACKGROUND
Many patients with coronavirus disease 2019 (COVID-19) have been diagnosed with computed tomography (CT). A prognostic tool based on CT findings could be useful for predicting death from COVID-19.
OBJECTIVES
To compare the chest CT findings of patients who survived COVID-19 versus those of patients who died of COVID-19 and to determine the usefulness the clinical usefulness of a CT scoring system for COVID-19.
METHODS
We included 124 patients with confirmed SARS-CoV-2 infections who were hospitalized between April 1, 2020 and July 25, 2020.
RESULTS
Whereas ground-glass opacities were the most common characteristic finding in survivors (75%), crazy paving was the most characteristic finding in non-survivors (65%). Atypical findings were present in 46% of patients. The chest CT score was directly proportional to mortality; a score ≥18 was the best cutoff for predicting death, yielding 70% sensitivity (95%CI: 47%-87%).
CONCLUSIONS
Our results suggest that atypical lesions are more prevalent in this cohort. The chest CT score had high sensitivity for predicting hospital mortality.
背景
许多新冠肺炎（COVID-19）患者已被诊断为计算机断层扫描（CT）。基于 CT 结果的预测工具可能有助于预测 COVID-19 死亡。
目的
比较 COVID-19 存活患者与 COVID-19 死亡患者的胸部 CT 表现，并确定 COVID-19 CT 评分系统的临床实用性。
方法
我们纳入了 2020 年 4 月 1 日至 7 月 25 日期间住院的 124 例确诊的 SARS-CoV-2 感染患者。
结果
磨玻璃影是幸存者最常见的特征性表现（75%），而铺路石征是非幸存者最特征性的表现（65%）。46%的患者存在不典型表现。胸部 CT 评分与死亡率直接相关；评分≥18 是预测死亡的最佳截断值，敏感性为 70%（95%CI：47%-87%）。
结论
我们的结果表明，在本队列中不典型病变更为常见。胸部 CT 评分对预测住院死亡率具有很高的敏感性。
