Mild traumatic brain injury is a significant public health issue that has been gaining considerable attention over the past few years. After injury, a large percentage of patients experience postconcussive symptoms that affect work and school performance and that carry significant medicolegal implications. Conventional imaging modalities (computed tomography and magnetic resonance imaging) are insensitive to microstructural changes and underestimate the degree of diffuse axonal injury and metabolic changes. Newer imaging techniques have attempted to better diagnose and characterize diffuse axonal injury and the metabolic and functional aspects of traumatic brain injury. The following review article summarizes the currently available imaging studies and describes the novel and more investigational techniques available for mild traumatic brain injury. A suggested algorithm is offered.
轻度创伤性脑损伤是一个重大的公共卫生问题，近年来受到了相当多的关注。受伤后，很大一部分患者会出现影响工作和学业表现的脑震荡后症状，并具有重要的医学法律意义。传统的成像方式（计算机断层扫描和磁共振成像）对微观结构的变化不敏感，低估了弥漫性轴索损伤和代谢变化的程度。更新的成像技术试图更好地诊断和描述创伤性脑损伤的弥漫性轴索损伤以及代谢和功能方面。本文综述了目前可用的成像研究，并描述了轻度创伤性脑损伤的新的和更具探索性的技术。提出了一个建议的算法。
