    侧副沟形态学及分叉点的立体定位研究

    The morphology and stereotaxy of bifurcation of the cerebral collateral sulcus

    • 摘要: 目的:探讨大脑侧副沟在MRI横断面及冠状面图像上的形态学规律。方法:在eFilm2.1工作站中,选取40名正常成人志愿者头颅连续MRI横断位及冠状位扫描数据,运用结构连续追踪法和3D-Cursor技术,对连续MRI横断面及冠状面图像上的侧副沟进行识别、观测,统计其形态学特征。结果:侧副沟分为三部分,即鼻嗅沟、中段侧副沟及枕部侧副沟;侧副沟在MRI冠状面图像上随着层面向后移而沟上移;枕部侧副沟在72.5%情况下出现分支,分为内、外侧支;侧副沟在冠状面映射长度=横断面层数×2 mm,其在横断面映射长度=冠状面层数×2 mm。结论:大脑侧副沟MRI横断面及冠状面图像上的形态学研究可为侧副沟及相邻脑区病变的识别和定位提供解剖学资料。

       

      Abstract: Objective:To explore the morphology of cerebral collateral sulcus(COS) on the MRI cross section and coronal plane image of brain.Methods:In the eFilm2.1 workstation, the continuously cross section and coronal plane MRI scanning data of 40 health adult volunteer brain were selected.The morphological characteristics of COS on the continuously cross section and coronal plane MRI were identified, observed and analyzed using the structure continuous tracking method and 3D-Cursor technology.Results:The collateral sulcus could be divided into the sulcus olfactorius nasi, middle collateral sulcus and occipital collateral sulcus.With the stratification plane rearward shift, the collateral sulcus on the coronal plane image moved upper.The 72.5% of occipital collateral sulcus was divided into the medial and lateral branches.The mapping length of collateral sulcus on the coronal plane and cross section plane equaled to the number of plies of cross section times 2 mm and number of plies of coronal plane times 2 mm, respectively.Conclusions:The morphological pattern of COS in the MRI cross and coronal-sectional images can provide the anatomical information for identifying and locating the collateral sulcus and its adjacent brain lesion.
