2019冠状病毒病（COVID-19）的爆发始于2019年12月，传播源假定位于中国武汉，并持续至今。随着COVID-19大流行在世界各国逐步蔓延，人们开始关注COVID-19肺炎的潜在长期后果。影像学在COVID-19肺炎的诊断和管理中发挥着核心作用，胸部X线检查和计算机断层扫描（CT）无疑是最广泛使用的方式，可以快速灵敏地检测与COVID-19肺炎相关的浸润模式。为了更好地了解肺损伤的潜在病理机制，纵向成像系列是必要的，其中CT是有限的可用性，由于重复暴露的X射线。MRI的最新进展表明，高性能低场MRI可能是一种有价值的方法，肺成像，而不需要辐射暴露。然而，到目前为止，低场MRI尚未应用于研究COVID-19肺炎后的肺损伤。我们提出了一个病例报告，患者患有COVID-19肺炎，在首次感染后三个月使用0.55 T MRI进行随访检查。低场MRI能够精确显示持续性肺部变化，包括磨玻璃样阴影，这与同一天进行的CT一致。低场MRI在检测COVID-19肺炎患者的肺部受累方面似乎是可行的，并且可能具有重复肺部检查的潜力，以监测肺部感染后的恢复情况。
The outbreak of coronavirus disease 2019 (COVID-19) with the origin of the spread assumed to be located in Wuhan, China, began in December 2019, and is continuing until now. With the COVID-19 pandemic showing a progressive spread throughout the countries of the world, there is emerging interest for the potential long-term consequences of suffering from a COVID-19 pneumonia. Imaging plays a central role in the diagnosis and management of COVID-19 pneumonia, with chest X-ray examinations and computed tomography (CT) being undoubtedly the modalities most widely used, allowing for a fast and sensitive detection of infiltration patterns associated with COVID-19 pneumonia. For a better understanding of underlying pathomechanisms of pulmonary damage, longitudinal imaging series are warranted, for which CT is of limited usability due to repeated exposure of X-rays. Recent advances in MRI suggested that high-performance low-field MRI might represent a valuable method for pulmonary imaging without the need of radiation exposure. However, so far, low-field MRI has not been applied to study pulmonary damage after COVID-19 pneumonia. We present a case report of a patient who suffered from COVID-19 pneumonia using 0.55 T MRI for follow-up examinations three months after initial infection. Low-field MRI enables a precise visualization of persistent pulmonary changes including ground-glass opacities, which are consistent with CT performed on the same day. Low-field MRI seems to be feasible in the detection of pulmonary involvement in patients with COVID-19 pneumonia and may have the potential for repetitive lung examinations in monitoring the reconvalescence after pulmonary infections.
