【摘要】 目的通过比较、分析常规Ｘ线平片、ＣＴ及ＭＲ在急性脊柱损伤中的影像改变、总结ＣＴ对急性脊柱损伤的诊断价值以及３种不同检查方法的适应症。方法拍受伤部位脊柱正、侧位Ｘ线法，环枢椎加拍开口位，腰骶部加拍双斜位等：并行ＣＴ检查。其中６位怀疑脊髓损伤的患者行ＭＲ检查。结果３种检查对显示椎体变形敏感性相同。在显示皮质及椎体内细小骨折线，椎间盘病变方面，ＣＴ与ＭＲ明显优于普通Ｘ线片在显示小关节、推弓与椎板的骨折方面，ＣＴ优于Ｘ线检查与ＭＲ。在显示脊髓损伤方面，ＭＲ明显优于ＣＴ与Ｘ线检查。结论常规Ｘ线法应做为首选取检查；有条件的患者均应做ＣＴ检查；怀疑脊损伤的患者应及时进行ＭＲ检查。更多还原

【Abstract】 Objective To evaluate the diagnostic value of CT imaging in the acute spinal injuries. Methods CT images were obtained in 54 cases with acute spinal injuries on the Elscint 2000. CT studies were compared with plain film in all cases, with 6 MAI cases. Results CT imaging was superior to the plain film and MRI in showing fracture of small joints and vertebral aches, vertebral plates. The impacted fractrue of vertebras bodies were shown well in all three methods. MRI was the best in finding myelonic injuries. Conclusion CT is the best method in the diagnosis of acute spinal injuries. Combination of CT with MRI can increase the diagnostic accuracy and can evaluate the treatment efficiency of myelonic injuries.更多还原
