摘要
目的提高腰椎间盘术前诊断水平,为手术科室提供更全面的影像信息。方法总结了25例临床诊断为腰椎间盘突出症患者,均有椎管造影、CTM检查及手术结果。CTM使用螺旋扫描,而后对原始图像进行多平面重建(MPR),得到轴位、矢状位及冠状位重建图像。结果经手术证实,椎管造影及CTM对腰椎间盘突出的诊断符合率分别是73.9%(17/23)与95.7%(22/23);CTM对4例外侧型椎间盘突出及3例椎体终板崩裂和1例椎弓峡部裂病例的术前诊断符合率为100%。结论CTM是腰椎间盘突出手术前可靠的检查方法,如果使用螺旋扫描+多平面重建(MPR)技术,则会进一步提高诊断的准确率。
Objective To improve diagnoses level of the lumbar intervertebral discs in front of the operation,and to provide much more all-around image information for the clinical surgery.Methods There are 25 cases the lumbar intervertebral discs herniation by clinician,and they all have the result of the spinal myelography、the computed tomography myelography(CTM) and the operation. The CTM is scanned by spiral CT scan,and the multiple plane rebuild the originality image,consequently gained the axial projection、the co...
