OBJECTIVE
To investigate the feasibility, accuracy of B ultrasound in the examination of joint space of lumbar spine facet joints compared with CT scan.
METHODS
Ten healthy adult volunteers were enrolled. The joint space of lumbar facet joints was measured by ultrasound. To identify the spinal levels, the posterior parasagittal sonograms were obtained at levels L1 to S1. The lumbar facet joints were delineated with the help of transverse sonograms at each level. Meanwhile, the lumbar facet joints were evaluated by spiral CT on the same plane, reformatted to 1-mm axial slices.
RESULTS
A total of 88 lumbar facet joints from L1 to S1 were clearly visualized in the 10 volunteers. Both ultrasound and CT measurements showed the same average depth and lateral distance of lumbar facet joint space (P > 0.05).
CONCLUSION
The lumbar facet joint space can be accurately demonstrated by ultrasound.
目的
与CT扫描相比，探讨B超检查腰椎小关节间隙的可行性及准确性。
方法
纳入10名健康成年志愿者。采用超声测量腰椎小关节间隙。为确定脊柱节段，在L1至S1水平获取后矢状旁超声图像。在每个水平借助横断超声图像勾勒出腰椎小关节。同时，在同一平面通过螺旋CT对腰椎小关节进行评估，并重建为1毫米轴向切片。
结果
10名志愿者中，L1至S1的88个腰椎小关节均清晰可见。超声和CT测量显示腰椎小关节间隙的平均深度和外侧距离相同（P>0.05）。
结论
超声可准确显示腰椎小关节间隙。
