| 摘 要： | 目的:建立CT/MRI配准和融合基础上的卵圆孔与半月神经节共存的手术界面,实现半月神经节与穿刺针关系的可视化。方法:将10例三叉神经痛患者的增强3d Fiesta序列的MRI数据和头颅CT数据导入surgView-RFT电磁导航系统,增强3d Fiesta上分割出半月神经节图像,单独保存。头颅增强3dFiesta和CT以鼻根点、双侧髁突外侧嵴点3点进行线性配准,在CT/MRI融合基础上二次融合半月神经节图像,建立卵圆孔与半月神经节共存的手术界面。结果:10例患者的20侧半月神经节均在增强3d Fiesta上被分割成像。经图像融合后卵圆孔与半月神经节的位置关系如下:冠状位、矢状位上半月神经节不位于卵圆孔开口区的为2/20,半月神经节位于卵圆孔开口区的为18/20。结论:CT/MRI整体配准和融合基础上的卵圆孔与半月神经节共存的导航手术界面,可以排除非靶组织的干扰,使靶点和穿刺针的关系更加简单明了,便于应用者识别,同时为实现分支选择性射频温控热凝术奠定基础。

| Abstract: | Objective:To modify the surgical interface,from the fusion of CT with foramen ovale(FO) and MRI with trigeminal ganglion(TGG) in navigation-guided radiofrequency thermocoagulation(RFT).Methods:10 trigeminal neuralgia patients were examined by CT scan and enhanced 3d Fiesta MRI scan.The data of CT and MRI scans was input into surgView-RFT electromagnetic navigation system.Trigeminal ganglion(TGG) was segmented out of enhanced 3d-Fiesta MRI scan.CT and MRI scans were fused according to root of nose and bilate... |
