目的:探讨多层螺旋CT(MSCT)扫描及重组技术在新旧性胸腰椎压缩骨折中的优势。方法:对84例新旧胸腰椎压缩骨折患者共95个椎体进行MSCT扫描检查,图像经二维和三维处理进行比较分析。结果:新鲜骨折56个椎体,陈旧骨折39个椎体,在新鲜与陈旧性椎体压缩性骨折中,以腰1最多,占28.57%(16/56)和35.89%(14/39),其次是胸12椎体、腰2椎体和胸11椎,在新鲜与陈旧性椎体压缩骨折CT表现中,骨折线清晰锐利(分别是51个和10个椎体),脊髓损伤(分别是8个和0个椎体),椎旁软组织影(分别是51个和5个椎体),附件骨折(分别是13个和2个椎体),椎体周围脏器挫裂伤(分别是15个和0个椎体),椎间盘真空征(分别是5个和19个椎间盘),椎体骨小梁结构紊乱硬化(分别是15个和25个椎体)。结论:MSCT扫描检查在鉴别大多数新旧性胸腰椎压缩骨折中具有重要作用,可大大提高诊断的准确性。
Objective: To investigate the advantages of multislice spiral CT (MSCT) scanning and reconstruction in old and new thoracolumbar vertebral compression fractures. Methods: A total of 95 vertebral bodies of 84 patients with old and new thoracolumbar fractures were examined by MSCT. The images were compared by two-dimensional and three-dimensional images. Results: 56 vertebral bodies with fresh fractures and 39 vertebral fractures with old vertebrae were the highest in the fresh and old vertebral compression fractures, accounting for 28.57% (16/56) and 35.89% (14/39), respectively, Followed by chest 12 vertebrae, lumbar 2 vertebrae and thoracic 11 vertebrae. In fresh and old vertebral compression fractures, the fracture lines were clear and sharp (51 and 10 vertebral bodies, respectively) and spinal cord injuries 8 and 0 vertebral bodies), paravertebral soft tissue (51 and 5 vertebral bodies, respectively), accessory fractures (13 and 2 vertebral bodies, respectively), vertebral body contusion and laceration 15 and 0 vertebral bodies), disc vacuum procedures (5 and 19 discs, respectively), and structural and trabecular dislocation of the vertebral bodies (15 and 25 vertebral bodies, respectively). Conclusion: The MSCT scan can play an important role in the identification of most new and old thoracolumbar vertebral compression fractures, which can greatly improve the diagnostic accuracy.
