We aimed to determine whether bone marrow edema (BME) in acute traumatic scaphoid fracture could be demonstrated with dual-energy CT (DECT) using MRI as the gold standard. In recent years, virtual non-calcium (VNCa) images have been used to demonstrate BME in trauma cases, for example, in vertebral compression fractures, hip trauma to detect occult fractures and knee fractures. We present three cases of acute scaphoid trauma. Two patients had subtle or invisible fractures on x-ray and conventional CT images, while DECT VNCa images clearly visualized the BME, which was confirmed by MRI. One patient had negative findings on both VNCa and MRI images. The DECT VNCa algorithm is a promising technique to demonstrate BME in scaphoid fractures, with potential for increasing the diagnostic value of CT in this type of injury.
我们旨在以磁共振成像（MRI）作为金标准，确定双能CT（DECT）能否显示急性创伤性舟状骨骨折中的骨髓水肿（BME）。近年来，虚拟去钙（VNCa）图像已被用于显示创伤病例中的BME，例如在椎体压缩骨折、髋部创伤以检测隐匿性骨折以及膝关节骨折中。我们展示了三例急性舟状骨创伤病例。两名患者在X线和传统CT图像上有细微或不可见的骨折，而DECT VNCa图像清晰地显示了BME，这一点通过MRI得到了证实。一名患者的VNCa和MRI图像均为阴性结果。DECT VNCa算法是一种显示舟状骨骨折中BME的有前景的技术，有可能提高CT在这类损伤中的诊断价值。
