目的 研究腰椎间盘突出在矢状位、冠状位上的CT表现。方法 对 42例 5 0个突出椎间盘在横断位扫描后 ,进行矢状位、冠状位上图像重建。结果 在矢状位上表现为突入椎管的软组织密度阴影 ,形态呈半圆形或椭圆形。在冠状位上呈钻头状 ,游离型椎间盘呈条索状 ,或不规则形。可远离椎间隙。结论 三维重建对腰椎间盘突出症有重要的诊断价值 ,可提供平片和横断位不易得到的解剖学信息。结合横断位可清晰地显示突出椎间盘的位置、形态特征以及病理分型。为临床治疗方案的选择提供可靠依据。
Objective To study the CT findings of lumbar disc herniation in the sagittal and coronal planes. Methods Twenty-two (42) cases of disc herniation were scanned in the transverse plane and reconstructed on sagittal and coronal planes. The results showed in the sagittal position into the soft tissue density of the shadow of the spinal canal, the shape was semicircular or oval. In the coronal bit was drilled, free-type intervertebral disc was cords, or irregular shape. Can stay away from the intervertebral space. Conclusion Three-dimensional reconstruction of the lumbar disc herniation has important diagnostic value, can provide plain and transverse section is not easy to get the anatomical information. Combined with transverse dislocation can clearly show the prominent disc position, morphological features and pathological type. Provide a reliable basis for the choice of clinical treatment options.
