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 investigate the diagnostic value of multislice spiral CT in occult atlantoaxial fractures. Methods Thirty-eight patients with fractures who were not found fractures after X-ray examination were retrospectively analyzed by spiral computed tomography (CT) with Vitrea workstation, MPR, MIP, VR and SSD were retrospectively analyzed. Radiologists to read the film together, based on the common opinion. Results Thirty-eight cases of fractures without X-ray were reconstructed by spiral CT. Twenty-eight cases showed hidden small fractures. Conclusions Multi-slice spiral CT two-dimensional and three-dimensional reconstruction of the diagnosis of occult vertebral axis fractures have an important value.
