摘要
目的探讨64层螺旋CT图像后处理技术在腰椎峡部裂诊断中的应用价值。方法应用64层螺旋CT对15例23处腰椎峡部裂患者的腰椎进行扫描,利用多平面重建(MPR)、最大密度容积显示(VRT)和曲面重建(CPR)进行多种图像后处理,观察腰椎峡部裂的显示情况,统计各种方法的显示率。结果对腰椎峡部裂的显示率MPR为100%(23/23),沿椎弓根走行的斜矢状位重建图像可显示椎弓峡部不规则骨质缺损及骨质边缘增生硬化;整体VRT为73.9%(17/23),立体切割VRT为100%(23/23);多层面多次连线成像CPR为100%(23/23),单次连线成像CPR为95.7%(22/23),各椎体的峡部均在一个平面完全显示。结论64层螺旋CT图像后处理技术能够全方位评价腰椎峡部裂的形态变化,为临床治疗提供参考和依据。
Objective To evaluate the value of post-processing technique in diagnosing lumbar spon- dylosehisis using 64-slice CT. Method Fifteen patients with lumbar spondyloschisis were underwent by 64-slice spiral CT. The data was transmitted to 3D workstation and the images were reconstructed with the techniques of muhiplanar reconstruction （MPR）, volume rendering （VR） and curved planar reconstruction （CPR） in order to observe the lesions of spondyloschisis. Results The display rate of spondyloschisis by MPR, VRT and CPR were 100% （23/23） , 73.9% （ 17/23 ）, 100% （23/23）, 95.7% （22/23）, 100% （23/23） respectively. All spondyloschisis can be totally showed by one image of CPR. Conclusion The post-processing technique of 64-slice CT yields more information of morphologic change of the lumbar spondyloschisis, providing more valid information for clinicians.
