目的:探讨螺旋CT平面重建对隐性骨折的诊断价值。方法:15例急性外伤患者均行X线平片检查,其中3例行螺旋CT平扫,12例同时行平面重建CT检查。结果:本组病例X线平片均未见骨折征象,受伤部位分别为近端胫骨6例,肘部2例,肩2例,髌骨1例,腕舟骨1例,耻骨支1例,腰椎椎体1例,颈椎1例。结论:螺旋CT扫描及平面重建CT检查能早期确诊隐性骨折,若急性外伤患者临床症状、体征严重,X线平片又未发现有明确骨折征象者,于X线检查后行螺旋CT扫描及平面重建CT检查应为最佳的检查手段。结合轴位及多平面像,可提供诊断信息,有助于临床处理。
Objective: To investigate the value of spiral CT reconstruction in the diagnosis of occult fracture. Methods: Fifteen patients with acute trauma were examined by X-ray plain film. Three patients underwent spiral CT scan and 12 patients underwent CT scan at the same time. Results: There were no signs of fracture on X-ray in this group. There were 6 cases of proximal tibia, 2 cases of elbow, 2 cases of shoulder, 1 case of patella, 1 case of scaphoid, 1 case of pubis and 1 case of lumbar spine 1 case of vertebral body, 1 case of cervical vertebra. Conclusion: Spiral CT scan and reconstructive computed tomography can diagnose latent fractures early. If the clinical symptoms and signs are serious in acute trauma patients, and no obvious fracture signs are found in X-ray plain film, spiral CT scan is performed after X-ray examination and Plane reconstruction CT examination should be the best means of inspection. Combined with axial and multiplanar images, diagnostic information is provided to aid in clinical management.
