Abstract： 目的 应用99Tcm-六甲基丙二基胺肟(HMPAO)SPECT显像和NEUROSTAT软件分析健康人的控尿脑激活区.方法 15名右利手健康男性志愿者(年龄24～45岁),在排空膀胱的静息状态和膀胱充满尿液的控尿状态接受2次显像.控尿状态图像由2次采集数据相减而获得.图像分析采用NEUROSTAT分析软件,进行多重对照校正(P＜0.05).结果 与静息状态相比,控尿状态下,两侧额下回和右侧颞上、中回的放射性明显增高,其中右侧额下回尤为突出.结论 健康男性控尿的大脑控制与两侧额下回和右侧颞上、中回密切相关,尤其右侧额下回在控尿的大脑控制中起重要作用.应用SPECT脑功能显像及NEUROSTAT分析软件可以确定控尿的大脑控制区,方法简便,易于推广.
