摘　　要：目的通过MRI检查成人脊髓圆锥末端位置的变化,为腰麻穿刺提供信息。方法 120例病人术前行腰部MRI扫描:正中矢状面测量脊髓圆锥末端的位置,并按脊柱单元分区。结果 120例脊髓圆锥末端位置与年龄、性别、身高、体重和体重指数无明显相关;范围在T12-L2-3水平,主要集中在T12-L1(15%)、L1U(21.7%)、L1M(23.3%)和L1L(18.3%)之间,8例位于L1-2水平以下,其中1例女性在L2-3水平。结论 MRI检查能够准确判断成人脊髓圆锥末端位置,为腰麻提供信息,避免穿刺时损伤脊髓。Objective To examine the changes of the position of adult spinal cord conus end by MRI, and provide information for spinal anesthesia puncture. Method 120 patients were given lumbar MRI scan before operation. The position of adult spinal cord co-nus end was measured at median sagittal plane and divided into partition according to spine unit. Result The position of spinal cord conus end of the 120 patients was not associated with age, sex, height, weight and body mass index, in the range of T12-L2-3 , mainly in T12-L1 （15% ）, L1 U （21. 7% ）, between L1 M （23. 3 % ） and L1 L （18. 3% ）, with 8 cases below L1-2 , in which one case of women was within L2-3 level. Conclusion MRI examination can accurately determine the adult spinal cord conus end position, pro-vide information for spinal anesthesia, and avoid puncture damage to spinal cord.
