摘  要:目的研究18F-脱氧葡萄糖(FDG)PET/CT显像在诊断意识障碍患者以及评估患者脑功能中的价值。方法回顾性分析2007年1月至2016年10月间40例植物状态(VS)患者(男26例、女14例,年龄17-73岁)、12例微意识状态(MCS)患者(男11例、女1例,年龄25。53岁)以及11例意识障碍后恢复清醒者(男10例、女1例,年龄12-68岁)各脑区的葡萄糖代谢情况,选取感兴趣区计算标准摄取值(SUV),并将3组患者进行对比。数据分析采用单因素方差分析和最小显著差异t检验。结果除脑干外,其余脑区SUV在VS、MCS、恢复清醒组间差异均有统计学意义(F值:6.214~13.642,均P〈0.01)。VS组患者大脑皮质各脑区SUV低于MCS组(t值:2.263-3.548,均P〈0.05);vs组患者大脑皮质和小脑SUV均低于恢复清醒组(t值:1.299~5.136,均P〈0.05);MCS组患者顶叶、颞叶、枕叶、丘脑、小脑的SUV均低于恢复清醒组(t值:1.962~2.841,均P〈0.05)结论18F-FDGPET/CT对评估意识障碍患者脑功能有重要意义。Objective To evaluate the changes of brain metabolism with 18F-fluorodeoxyglucose (FDG) PET/CT in patients with disorders of consciousness (DOC). Methods This retrospective study, from January 2007 to October 2016, included 40 patients (26 males, 14 females, age range: 17-73 years) in the vegetative state (VS), 12 patients (11 males, 1 female, age range: 25-53 years) in the minimally conscious state (MCS), and 11 patients (10 males, 1 female, age range: 12-68 years) in the state of re- covering from DOC. All patients underwent ISF-FDG PET/CT imaging. The standardized uptake value (SUV) of multiple brain areas among 3 groups of patients was calculated and compared. One-way analysis of variance was used for data analysis. Results The SUV in different encephalic regions among 3 groups were significantly different (F values: 6.214-13.642, all P〈0.01 ) except for mesencephalon. Compared with MCS group, the SUV of cerebral cortex of VS group was lower ( t values : 2.263-3. 548, all P〈0.05). Com- pared with the recovered group, the SUV of cerebral cortex and cerebellum of VS group was lower ( t values : 1. 299-5.136, all P〈0.05). Compared with the recovered group, the SUV of parietal lobe, temporal lobe, occipital lobe, thalamus and cerebellum of MCS group was lower (t values: 1.962-2.841, all P〈0.05 ). Conclusion lSF-FDG PET/CT may be significant in evaluating brain function of DOC patients.
