摘　　要：目的探讨多层螺旋CT对寰枢椎隐匿性骨折诊断价值。方法对38例X线平片检查后未发现骨折而临床怀疑有骨折的患者行螺旋CT扫描,通过Vitrea工作站对其进行后处理(MPR、MIP、VR及SSD),重建图像由2位有经验的放射科医师共同阅片,以共同意见为准。结果38例X线平片中未显示骨折的患者经螺旋CT重建后,28例显示有隐匿的细小骨折。结论多层螺旋CT二维和三维重建对环枢椎隐匿性骨折的诊断具有重要价值。Objective To discuss the diagnostic value of multi - slice spiral CT 2D and 3D reconstruction for atlantoaxial occult fracture. Methods Multi - slice spiral CT scans were performed in 38 patients who were suspected of fracture but were not detected with radiography, and the images were post - processed with Vitrea workstation （including MPR, MIP, VR and SSD）. The images were observed by two experienced radiologists. Results Of 38 cases,28 cases were detected having small fractures with spiral CT reconstruction. Conclusion Multi-slice spiral CT 2D and 3D reconstructions are of important value in diagnosing atlantoaxial occult fracture.
