摘要严重颅脑损伤所致植物状态预后具有很大的差异，其意识不同水平决定着植物状态临床治疗和家庭护理的延续，因此准确判断意识障碍的类型和程度具有重要的临床指导意义。PET/CT通过放射性示踪剂定量反映大脑功能变化和残存活性，为意识障碍患者的诊断及预后评估提供客观依据。本文就PET/CT在颅脑损伤意识障碍诊断中的应用和大脑功能变化研究进展做一综述。

Abstract：Patients with severe traumatic brain injury often survive in vegetative state, and show a significant difference in the prognosis. The level of consciousness in these patients decides whether the clinical treatment and home care for them to be continued or not, thus it makes great sense in the diagnosis of the type and degree of disorders of consciousness. The degree of brain dysfunction can reflect the level of consciousness, PET/CT quantitatively shows the change of brain function and corresponding residual activity area by using radioactive tracer, and further provides the clinical objective evidence for the diagnosis and prognosis assessment. Then this article will make a summary on the research progress of PET/CT about residual brain’s function and diagnosis of disorders of consciousness in traumatic brain injury.
