摘　　要：目的 :研究椎间盘突出的三维定位 ,为腰椎间盘突出患者提供更精确的诊断依据。方法 :对 40例椎间盘突出CT扫描后进行多平面重建 ,得到矢状位图像。用 1～ 4四个数字代表突出髓核在横断位上的位置 ,在横断位或矢状位上测量髓核后突的程度 ,在矢状位上测量髓核上下移位的长度。按照左右、前后、上下的顺序来描述髓核突出的部位、后突程度和长度 ,并与手术结果对照。结果 :三维定位提供的部位、程度和长度与手术结果相符。结论 :多平面重建图像和三维定位方法是可靠的 。Objective:To Obtain an accurate diagnosis of the lumbar disc herniation,a three dimensional localization study was carried out.Method:The herniated discs of forty patients were examined utilizing CD scan and multi planer reconstruction.The numbar 1 to 4 was defined as the position of the herniated disc in transverse plane,and the measurements of its size and displacement were obtained through transverse and sagittal images.The results of measurements were compared with the surgical findings.Result:Three dimensional localization and measurement of herniation disc were correlated with the surgical findings.Conclusion:Multi planar reconstruction and the three dimensional localization of the herniated disc is valuable for the accurate diagnosis of lumbar disc herniation.
