摘要
目的:讨论MSCT斜冠状面重建显示腰椎小关节损伤的临床价值。方法:MSCT行腰椎扫描172例,扫描重建层厚2mm,间隔1mm,将数据行MPR处理;利用主机工作站的"脊柱智能间盘成像(Spine MPR)"技术,研究在矢状面定位像上对L1～S1各个椎间小关节进行平行于小关节间隙的轴向倾斜重建。通过操作使各个椎小关节都得到一组平行的轴位图像。结果:MPR重建后图像可以在另一角度清晰显示腰椎小关节上下关节突,对小关节突病变显示清楚。结论:多层螺旋CT结合进行斜冠状面重组技术能清晰显示腰椎小关节突病变,较常规的横断扫描更有重要价值。
Objective： To evalute the clinical value of Oblique coronal plane with Multislice spiral CT （MSCT） in the diagnosis of facet joint injury of lumbar. Methods： 172 eases of lumbar MSCT scanning, scan reconstruction slice thickness 2mm,interval of 1mm, the data line MPR processing;use the host＂Spine MPR＂ technology, research orientation in the sagittal plane as on L1 - S1 every facet joints parallel to the facet joint in the axial tilt reconstruction. Through the operation so that each facet joints have been a set of parallel axial images. Results： MPR images could show reconstructed in another point of view clearly shows the upper and lower lumbar facet joints, facet joint disease on the display clearly. Conclusion： MSCT combined with oblique coronal reeombination can clearly show the lumbar facet joint disease,is more than the conventional cross -sectional scanning important value.
