摘要
目的:研究多导睡眠监测联合磁共振动脉自旋标记灌注检查在失眠症诊断中的应用.方法:神经内科门诊收治的失眠症患者42名为研究对象,同期纳入对照组41名.对两组患者进行睡眠习惯问卷和医院焦虑抑郁量表评估,多导睡眠监测和磁共振动脉自旋标记灌注扫描.结果:失眠组入睡所需时间显著多于对照组(P<0.05),睡眠时长显著短于对照组(P<0.05);两组患者焦虑抑郁水平无显著差异;失眠组患者总睡眠时间及快动眼睡眠时间显著短于对照组(P<0.05),睡眠潜伏期显著高于对照组(P>0.05),非快动眼睡眠S1期显著高于对照组(P<0.05),而S2～S4期显著短于对照组(P<0.05);失眠组患者双侧前额叶、右侧颞叶、左侧顶叶、右侧丘脑、脑桥等区域灌注均显著升高(P<0.05),而双侧岛叶、双侧基底节等区域灌注均显著降低(P<0.05).结论:多导睡眠监测联合磁共振动脉自旋标记灌注检查能够精确量化睡眠情况.
Abstract
Objective To explore the application of polysomnography combined with arterial spin labeling(ASL)perfusion magnetic resonance imaging in the diagnosis of insomnia.Methods Forty-two insomnia patients admitted to Department of Neurology were included as insomnia group,while 41 healthy subjects during the same period were included as control group.The two groups were assessed using sleep habits questionnaire,hospital anxiety and depression scale,polysomnography,and ASL perfusion magnetic resonance imaging.Results Compared with control group,insomnia group took significantly more time to fall asleep(P<0.05),and has shorter sleep duration(P<0.05).The differences in the levels of anxiety and depression between two groups were trivial.The total sleep time,rapid eye movement sleep duration,and non-rapid eye movement sleep stage S2-S4were shorter,while the sleep latency and non-rapid eye movement sleep stage S1were longer in insomnia group as compared with control group(all P<0.05).In insomnia group,perfusion was increased in bilateral prefrontal lobes,right temporal lobe,left parietal lobe,right thalamus,and pons(P<0.05),but decreased in bilateral insula and bilateral basal ganglia(P<0.05).Conclusion The combination of polysomnography and ASL perfusion magnetic resonance imaging enables precise quantification of sleep condition.
