Abstract：
UNASSIGNED: To evaluate and compare magnetic resonance imaging (MRI) sequences that could potentially be used in the diagnosis of coronavirus disease 2019 (COVID-19).
UNASSIGNED: Included in the study were 42 patient who underwent thorax computed tomography (CT) for COVID-19 pneumonia and thorax MRI for any reason within 24 h after CT. The T2-weighted fast spin echo periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) (T2W-FSE-P), fast imaging employing steady-state acquisition, T2 fat-saturated FSE, axial T1 liver acquisition with volume acceleration (LAVA) and single-shot FSE images were compared in terms of their ability to show COVID-19 findings.
UNASSIGNED: The mean age of the patients was 47.2 ± 24 years. Of the patients, 22 were male (52.4%) and 20 (47.6%) were female. The interobserver intraclass coefficient (ICC) for the image quality score was the highest in the T2W-FSE-P sequence and lowest in the T1 LAVA sequence. All of the lesion-based evaluations of the interobserver agreement were statistically significant, with the kappa value varying between 0.798 and 0.998.
UNASSIGNED: All 5 sequences evaluated in the study were successful in showing the parenchymal findings of COVID-19. Since the T2W-FSE-P sequence had the best scores in both interobserver agreement and ICC for the image quality score, it was considered that it can be included in thorax MRI examinations to assist the diagnosis of COVID-19.

摘要：
■评估和比较可能用于诊断2019年冠状病毒病（COVID-19）的磁共振成像（MRI）序列。
■该研究包括42例患者，他们在CT后24小时内因任何原因接受了COVID-19肺炎的胸部计算机断层扫描（CT）和胸部MRI检查。T2加权快速自旋回波周期性旋转重叠的平行线与增强重建（PROPELLER）（T2W-FSE-P），采用稳态采集的快速成像，T2脂肪饱和FSE，在显示COVID-19发现的能力方面，比较了轴向T1肝脏采集与体积加速（LAVA）和单次FSE图像。
■患者的平均年龄为47.2±24岁。在患者中，男性22人（52.4%），女性20人（47.6%）。图像质量评分的观察者间组内系数（ICC）在T2W-FSE-P序列中最高，在T1LAVA序列中最低。所有基于病变的观察者间协议评估均具有统计学意义，kappa值在0.798和0.998之间变化。
■研究中评估的所有5个序列都成功显示了COVID-19的实质发现。由于T2W-FSE-P序列在观察者之间的一致性和ICC中的图像质量得分都是最好的，认为可将其纳入胸部MRI检查以辅助COVID-19的诊断。
