目的探讨功能磁共振成像（fMRI）中健康受试者区域均匀性（ReHo）的性别差异。方法20例健康受试者（男10例，女10例）分别在正常睡眠（NS）和24 h睡眠剥夺（SD）后进行MRI检查。数据分析采用ReHo法，SPM5软件进行t检验，P值为0.001，以聚类体积≥270 mm3判定有无统计学意义。结果NS和SD术后均存在性别差异。结论ReHo能较好地反映NS和SD后健康受试者的性别差异。
Objective To explore the gender differences in regional homogeneity(ReHo) of healthy subjects in functional magnetic resonance imaging(fMRI).Methods Twenty healthy subjects(ten males and ten females) were underwent the MRI exams twice:after normal sleep(NS) and 24 h sleep deprivation(SD).ReHo method was used to analyze the data,SPM5 software was used to perform t-test with a P value0.001 and cluster volume≥270 mm3 was used to determine statistical significance.Results There exists gender differences both after NS and SD.Conclusions ReHo can well reflect gender differences of healthy subjects after NS and SD.
