多层螺旋CT在足踝部外伤诊断中的优势

The Advantages of Multi-slice Spiral CT in the Diagnosis of Foot and Ankle Trauma

目的探讨多层螺旋CT在足踝部外伤诊断中的优势。方法回顾性分析86例足踝部外伤患者的普通X线片和多层螺旋CT检查图像。结果普通X线片发现骨折75例,多层螺旋CT发现骨折82例,比普通X线多7例,23处,多层螺旋CT及其三维后处理技术MPR、MIP、SSD联合运用能全面显示足踝部骨折情况,减少漏诊,为临床提供更加有意义的信息。结论多层螺旋CT在足踝部外伤诊断中有明显的优势。

Objective To evaluate the advantage of multi-slice spiral CT in the diagnosis of foot and ankle trauma. Methods The 86 cases of foot and ankle trauma patients with normal X-ray and multi-slice spiral CT image were analyzed retrospectively. Resrlts Normal X-ray found fractures in 75 cases, multi-slice spiral CT found fractures in 82 cases,7 cases more than normal X-ray, 23, multi-slice spiral CT and 3 D postprocessing techniques of MPR, MIP, SSD combination can completely show the situation of ankle fracture, reduce misdiagnosis, provide more information for clinical significance. Conclusion Multi-slice spiral CT has obvious advantages in the diagnosis of foot and ankle trauma.
