摘要
目的研究腰椎峡部裂的矢状位重建诊断。方法对20例椎弓峡部裂的病例进行CT扫描和多平面重建,获得矢状位图像。随机选择3具经福尔马林固定过的腰椎标本直接矢状位扫描和横断位扫描,再将横断位扫描的图像重建成矢状位和三维图像。结果在直接矢状位上腰椎椎弓峡部显示良好,上、下关节突及椎弓峡部和椎弓根同时显示在同一图像上,矢状位重建图像与直接矢状位图像完全一致。在20例椎弓峡部裂病例中单腰椎19例,双腰椎1例,裂隙的形态及角度显示良好。结论矢状位重建可清晰的显示椎弓和椎弓峡部裂的形态特征。
Objective ： To study the MPR diagnosis of the lumbar spondylolysis. Material and Methods ： CT scan and MPR performed in 10 cases with spondylolysis,obtained the sagittal reconstruction imaging. We also studied 3 cadaver specimen lumbar spines,obtained as blocks of tissue, and scanned in the sagittal and axial planes with CT,then the MPR imaging were performed with axial imagings, and the cadaver lumbar spine blocks were anatomized. The reformated sagittal imaging were correlatively with the direct sagittal scan imaging. Results ：The isthmus and superior articular process and inferior articular process and pedicle of vertebral arch showed in the same direct sagittal scan imaging very clearly. Despite the reconstruction sagittal imagings cannot be evaluation as well by direct sagittal scan imaging. The informations of the direct sagittal scan can be displayed on reconstruction sagittal imaging. In 10 cases with lumbar spondylolysis, nine of them were single lumbar vertebral, one of them was two lumbar vertebrals. The shape and angle of the fissure of spondylolysis can be showed very clearly. Conclusion： Sagittal reconstruction can completely display the isthmus of vertebral arch and the features of spondylolysis in detail.
