基于计算机断层扫描（CT）和磁共振成像（MRI），对包括运动相关脑震荡（SRC）在内的轻度创伤性脑损伤（mTBI）的常见神经影像学表现进行了综述。在受伤当天通过放射学检查（通常为CT扫描）确定的常见异常表现为挫伤、蛛网膜下或脑实质内小肿块以及硬膜下和硬膜外积液、水肿和颅骨骨折。MRI常见的随访神经影像学结果包括白色高信号（WMH）、反映既往出血的低信号异常、局灶性脑软化、萎缩和/或Virchow-Robins血管周围间隙扩张。一项大型儿科mTBI研究的MRI结果显示，损伤后6个月时阳性MRI结果的频率较低。审查的结论与检查的一些先进的MRI为基础的图像分析方法，可以在病人谁持续mTBI进行。
Common neuroimaging findings in mild traumatic brain injury (mTBI), including sport-related concussion (SRC), are reviewed based on computed tomography (CT) and magnetic resonance imaging (MRI). Common abnormalities radiologically identified on the day-of-injury, typically a CT scan, are in the form of contusions, small subarachnoid or intraparenchymal hemorrhages as well as subdural and epidural collections, edema and skull fractures. Common follow-up neuroimaging findings with MRI include white matter hyperintensities (WMHs), hypointense signal abnormalities that reflect prior hemorrhage, focal encephalomalacia, presence of atrophy and/or dilated Virchow-Robins peri-vascular space. The MRI findings from a large pediatric mTBI study show low frequency of positive MRI findings at 6 months post-injury. The review concludes with an examination of some of the advanced MRI-based image analysis methods that can be performed in the patient who has sustained an mTBI.
