目的：通过在影像图像上对视神经管各解剖径线的测量，加深对视神经管解剖的认识，对视神经管及视神经的各类病变起指导作用。方法：随机选取正常无眼部及相关疾病成人50例(年龄18～60岁，男女各25例)行眼眶CT扫描，图像传入 Vitrea 后处理工作站，行 MPR 和3D 重建，测量其径线长度。结果：内壁右(12.69±2.10)mm、左(12.43±2.40mm)，外壁右(10.23±1.74)mm、左(10.15±1.72)mm，上壁右(10.08±1.89)mm、左(10.17±1.71mm)，下壁右(7.42±1.71)mm、左(6.86±1.59)mm；右眶口上下径(5.96±1.21)mm、左右径(4.83±1.08)mm，左眶口上下径(6.16±0.88)mm、左右径(4.93±1.25)mm，右中部上下径(4.22±0.54)mm、左右径(3.74±0.41)mm，左中部上下径(4.08±0.38) mm、左右径(4.15±0.28)mm，右颅口上下径(4.28±0.77)mm、左右径(5.36±1.04)mm，左颅口上下径(4.16±0.75)mm、左右径(5.27±1.07)mm。结论：视神经管测量必须薄层高分辨率扫描，并用骨算法重建，数据才准确；测量中必须左右分开测量，并结合斜冠状位和斜矢状测量才准确；视神经管四壁中，内侧壁最长也最薄，也是经常发生骨质缺损的部位；视神经管眶口呈竖椭圆形，中部呈圆形，颅口呈横椭圆形。
目的：通過在影像圖像上對視神經管各解剖徑線的測量，加深對視神經管解剖的認識，對視神經管及視神經的各類病變起指導作用。方法：隨機選取正常無眼部及相關疾病成人50例(年齡18～60歲，男女各25例)行眼眶CT掃描，圖像傳入 Vitrea 後處理工作站，行 MPR 和3D 重建，測量其徑線長度。結果：內壁右(12.69±2.10)mm、左(12.43±2.40mm)，外壁右(10.23±1.74)mm、左(10.15±1.72)mm，上壁右(10.08±1.89)mm、左(10.17±1.71mm)，下壁右(7.42±1.71)mm、左(6.86±1.59)mm；右眶口上下徑(5.96±1.21)mm、左右徑(4.83±1.08)mm，左眶口上下徑(6.16±0.88)mm、左右徑(4.93±1.25)mm，右中部上下徑(4.22±0.54)mm、左右徑(3.74±0.41)mm，左中部上下徑(4.08±0.38) mm、左右徑(4.15±0.28)mm，右顱口上下徑(4.28±0.77)mm、左右徑(5.36±1.04)mm，左顱口上下徑(4.16±0.75)mm、左右徑(5.27±1.07)mm。結論：視神經管測量必鬚薄層高分辨率掃描，併用骨算法重建，數據纔準確；測量中必鬚左右分開測量，併結閤斜冠狀位和斜矢狀測量纔準確；視神經管四壁中，內側壁最長也最薄，也是經常髮生骨質缺損的部位；視神經管眶口呈豎橢圓形，中部呈圓形，顱口呈橫橢圓形。

Objective:Through measuring the anatomic diameter on image visual for optic canal,to deepen our understanding of the anatomy of optic canal,to play the role of guidance of optic canal and various lesions of optic nerve.Methods:50 cases of adult without eye and related diseases were selected(age 18 to 60 years old,male and female with 25 cases in each).They were given orbital CT scan.The image was passed into the Vitrea post-processing workstation for MPR and 3D reconstruction.We measured its diameter line length.Results:The inner wall:right (12.69±2.10)mm,left(12.43±2.40)mm;the outer wall: right (10.23±1.74) mm,left(10.15 ± 1.72)mm;the upper wall:right (10.08 ± 1.89)mm,left(10.17 ± 1.71)mm;the lower wall:right (7.42 ± 1.71)mm, left(6.86±1.59)mm).The right orbital opening:top and bottom diameter(5.96±1.21)mm,from left to right diameter(4.83±1.08)mm;the left orbital opening: upper and lower size (6.16 ±0.88)mm,from left to right diameter (4.93±1.25)mm;right middle:top and bottom diameter(4.22±0.54)mm,from left to right diameter(3.74±0.41)mm;the left middle:top and bottom diameter(4.08±0.38) mm,from left to right diameter(4.15±0.28)mm;right cranial mouth:the upper and lower size(4.28±0.77)mm,from left to right diameter(5.36±1.04)mm;the left cranial mouth:upper and lower size(4.16±0.75)mm,from left to right diameter(5.27±1.07)mm. Conclusion:Optic canal measurement need high-resolution scanning,and bone algorithm reconstruction,and the data is accurate. In the measurement,the measurement must be parted for right and left,and should combine oblique coronal and oblique sagittal, measurement is accurate.The inner wall is the longest and most thin,also with bone defect.Optic canal orbital opening is elliptical;the central part is round;cranial mouth is ellipse.
