One of the paramount concerns in head injury is why there is such a disparity in recovery from injuries that appear clinically similar. CT scan has established itself as the primary imaging modality for acute head injury, and acute hemorrhages are readily identified allowing for prompt surgical intervention. However, CT has proven to be of little value in predicting the outcome of patients with diffuse nonhemorrhagic white-matter injury. Future research with MR imaging during the acute phase as well as continued work in the subacute and chronic phases will undoubtedly prove this modality useful in more precise prediction of outcome in patients with head injuries.
头部损伤最主要的问题之一是，为何临床上看似相似的损伤在恢复情况上存在如此大的差异。CT扫描已成为急性头部损伤的主要成像方式，急性出血很容易被识别出来，以便能迅速进行手术干预。然而，事实证明，CT在预测弥漫性非出血性白质损伤患者的预后方面价值不大。在急性期使用磁共振成像的未来研究，以及在亚急性期和慢性期持续开展的工作，无疑将证明这种成像方式在更精确预测头部损伤患者的预后方面是有用的。
