PET在创伤性颅脑损伤中的应用及进展

Clinical applications of PET imaging in patients with traumatic brain injury

创伤性颅脑损伤对人类健康危害巨大。传统的CT、MRI检查手段主要反映患者脑部形态结构的改变，结合PET后可以同时了解脑代谢功能的改变，在创伤性脑损伤诊断、治疗、预后评估等方面都有良好的价值。笔者对近年来PET在创伤性颅脑损伤中的应用作一综述。

Traumatic brain injury （TBI） is one of the leading causes of death and disability world- wide, particularly in young adults. Conventional imaging modalities such as CT or MRI can show most of the morphological changes of the brain in TBI. PET/CT and PET/MR can acquire both functional and morpho- logical images compared with CT or MRI alone, which might be helpful for the diagnosis, management and prognosis evaluation of TBI. This review summarizes the applications of PET imaging in TBI patients.
