Traumatic bone marrow lesions (TBMLs) are considered to represent a range of concealed bone injuries, including haemorrhage, infarction, and localised oedema caused by trabecular microfracture occurring in the cancellous bone. If TBMLs are not managed timeously, they potentially cause a series of complications that can lead to irreversible morbidity and prolonged recovery time. This article reviews interesting image findings of bone marrow lesions in dual-energy computed tomography (DECT). In addition to combining the benefits of traditional CT imaging, DECT also reveals and identifies various structures using diverse attenuation characteristics of different radiographic spectra. Therefore, DECT has the capacity to detect TBMLs, which have traditionally been diagnosed using MRI. Through evaluating DECT virtual non-calcium maps, the detection of TBMLs is rendered easier and more efficient in some acute accidents.
创伤性骨髓损伤（TBMLs）被认为代表一系列隐匿性骨损伤，包括松质骨中发生的小梁微骨折引起的出血、梗死和局部水肿。如果TBMLs未得到及时处理，它们可能会导致一系列并发症，进而导致不可逆的发病情况和延长恢复时间。本文综述了双能计算机断层扫描（DECT）中骨髓损伤的有趣影像表现。除了结合传统CT成像的优点外，DECT还利用不同射线光谱的不同衰减特性来显示和识别各种结构。因此，DECT有能力检测传统上通过MRI诊断的TBMLs。通过评估DECT虚拟非钙图，在一些急性事故中，TBMLs的检测变得更容易、更高效。
