The symptoms and findings of a concussion reflect a complex series of events that occur in the brain after a concussive injury. Because sports-related concussions do not cause structural lesions that can be identified with traditional neuroimaging techniques, determining concussion severity and when the brain has recovered sufficiently to permit safe return to play is challenging. Current concussion management using symptom monitoring, physical examination, and neurocognitive testing is limited in its ability to assess the extent of injury and recovery. This article reviews several advanced neuroimaging techniques that have the potential to provide more objective data to assist clinicians in the care of the athlete with concussion.
脑震荡的症状和检查结果反映了脑震荡损伤后大脑中发生的一系列复杂事件。由于与运动相关的脑震荡不会导致可通过传统神经影像学技术识别的结构性病变，因此确定脑震荡的严重程度以及大脑何时已充分恢复以允许安全重返赛场具有挑战性。目前使用症状监测、体格检查和神经认知测试的脑震荡管理在评估损伤程度和恢复情况方面能力有限。本文综述了几种先进的神经影像学技术，这些技术有可能提供更客观的数据，以协助临床医生护理脑震荡运动员。
