To evaluate the performance of 1.5 T true fast imaging with steady state precession (TrueFISP) magnetic resonance imaging (MRI) sequences for the detection and characterization of pulmonary abnormalities caused by coronavirus disease 2019 (COVID-19).
In this retrospective single-center study, computed tomography (CT) and MRI scans of 20 patients with COVID-19 pneumonia were evaluated with regard to the distribution, opacity, and appearance of pulmonary lesions, as well as bronchial changes, pleural effusion, and thoracic lymphadenopathy. McNemar's test was used in order to compare the COVID-19-associated alterations seen on CT with those seen on MRI.
Ground-glass opacities were better visualized on CT than on MRI ( = 0.031). We found no statistically significant differences between CT and MRI regarding the visualization/characterization of the following: consolidations; interlobular/intralobular septal thickening; the distribution or appearance of pulmonary abnormalities; bronchial pathologies; pleural effusion; and thoracic lymphadenopathy.
Pulmonary abnormalities caused by COVID-19 pneumonia can be detected on TrueFISP MRI sequences and correspond to the patterns known from CT. Especially during the current pandemic, the portions of the lungs imaged on cardiac or abdominal MRI should be carefully evaluated to promote the identification and isolation of unexpected cases of COVID-19, thereby curbing further spread of the disease.
评估1.5T稳态进动快速成像（TrueFISP）磁共振成像（MRI）序列在检测和鉴别2019冠状病毒病（COVID-19）所致肺部异常方面的性能。
在这项回顾性单中心研究中，对20例COVID-19肺炎患者的计算机断层扫描（CT）和MRI扫描结果进行了评估，内容包括肺部病变的分布、密度及表现，以及支气管改变、胸腔积液和胸部淋巴结病。采用McNemar检验比较CT和MRI上所见的与COVID-19相关的改变。
磨玻璃影在CT上比在MRI上显示得更好（ = 0.031）。我们发现，在以下方面，CT和MRI之间在显示/鉴别上没有统计学显著差异：实变；小叶间/小叶内间隔增厚；肺部异常的分布或表现；支气管病变；胸腔积液；以及胸部淋巴结病。
COVID-19肺炎所致肺部异常可在TrueFISP MRI序列上检测到，且与CT上已知的表现相符。特别是在当前大流行期间，应仔细评估心脏或腹部MRI所成像的肺部区域，以促进对意外COVID-19病例的识别和隔离，从而遏制疾病的进一步传播。
