X-ray imaging plays a crucial role in the confirmation of COVID-19 pneumonia. Chest X-ray radiography and CT are two major imaging techniques that are currently adopted in the diagnosis of COVID-19 pneumonia. However, dual-energy subtraction radiography is hardly discussed as potential COVID-19 imaging application. More advanced X-ray radiography equipment often supports dual-energy subtraction X-ray radiography. Dual-energy subtraction radiography enables the calculation of pseudo-radiographs, in which bones are removed and only soft-tissues are highlighted. In this commentary, the author would like to draw the attention to the potential use of dual-energy subtraction X-ray radiography ( soft-tissue pseudo-radiography) for the assessment and the longitudinal follow-up of COVID-19 pneumonia.
X 射线成像在 COVID-19 肺炎的确诊中起着至关重要的作用。胸部 X 射线摄影和 CT 是目前用于 COVID-19 肺炎诊断的两种主要成像技术。然而，双能减影射线摄影作为潜在的 COVID-19 成像应用几乎没有被讨论过。更先进的 X 射线摄影设备通常支持双能减影 X 射线摄影。双能减影射线摄影可以计算出伪射线照片，其中骨骼被去除，只突出软组织。在这篇评论中，作者希望引起人们对双能减影 X 射线摄影（软组织伪射线摄影）在 COVID-19 肺炎评估和纵向随访中的潜在用途的关注。
