骨挫伤作为隐匿性损伤,一般不能被X线、普通CT所诊断。虽然核医学对骨损伤检测敏感性很高,超声对于骨损伤周围软组织改变具有较高的敏感性,但两者对于骨损伤诊断的特异度均不高。磁共振成像(MRI)是目前检测骨挫伤的主要影像学方法,但临床上不是所有关节创伤患者均能进行常规MRI检查。双能CT(DECT)可通过虚拟去钙技术对骨髓病灶评估,快捷地判断是否存在可能的骨挫伤。DECT对骨挫伤的诊断是对MRI的重要补充。
Bone contusion as an occult injury, generally can not be X-ray, CT diagnosis. Although nuclear medicine is highly sensitive to the detection of bone damage and ultrasound is sensitive to the changes of soft tissues around the bone, the specificity of the two methods for the diagnosis of bone damage is not high. Magnetic resonance imaging (MRI) is the main imaging method for the detection of bone contusion at present, but not all patients with traumatic joint injury can perform routine MRI examination clinically. Dual-energy computed tomography (DECT) evaluates bone marrow lesions with virtual calcium-removal techniques to quickly determine if there is a possible bone contusion. DECT diagnosis of bone contusion is an important complement to MRI.
