【摘要】：目的:探討基于MRI圖像的大腦外側裂立體定向解剖學及其在腦立體定向手術中的意義。方法:采集30名健康成年自愿者的腦MRI圖像,經圖像轉換和配準,在標準三維立體坐標系中測量,以外側裂的外側緣為起點,向內沿X軸方向每3 mm為一取樣點直到島蓋內側面,記錄各取樣點的X、Y值,Z值為所在層面與AC-PC層面間層數(shù)與層距的積,統(tǒng)計所有取樣點的三維坐標值,建立大腦外側裂三維立體定位數(shù)據(jù)集。將所有外側裂外側緣取樣點坐標值進行分析,繪制其在矢狀和冠狀面上的投影圖。結果:成功構建大腦外側裂立體定位數(shù)據(jù)集;對30例出外側裂外側緣的投影圖進行分析,找出了外側裂的走行特點,并求出了回歸方程。結論:大腦外側裂立體定向解剖學研究,可為腦的立體定向手術及腦圖譜的建立提供解剖學資料。
[Abstract]:Objective: to investigate the stereotactic anatomy of lateral cerebral fissure based on MRI images and its significance in stereotactic brain surgery. Methods: brain MRI images of 30 healthy adult volunteers were collected and measured in standard three-dimensional coordinate system by image conversion and registration. The lateral margin of lateral fissure was taken as the starting point. Every 3 mm direction along the X axis is a sampling point up to the inner side of the island cover. The XY value and Z value of each sampling point are recorded as the product of the number of layers and the distance between the layers in the plane and the AC-PC layer, and the three dimensional coordinate values of all the sampling points are counted. To establish the three dimensional stereotaxic data set of lateral cerebral fissure. The coordinate values of all the sampling points in the lateral margin of the lateral fissure were analyzed, and the projection maps on the sagittal and coronal planes were drawn. Results: the stereotactic data set of lateral cerebral fissure was constructed successfully, and the projection map of 30 cases with lateral fissure lateral margin was analyzed, and the characteristics of lateral fissure were found out, and the regression equation was obtained. Conclusion: the study of stereotactic anatomy of lateral cerebral fissure can provide anatomical data for stereotactic operation and establishment of cerebral atlas.
