摘　　要：目的探讨^(99)TCm-MDP SPECT/CT融合显像在司法鉴定鼻骨新鲜/陈旧骨折中的应用价值。方法回顾性分析我院22例外伤后CT不能明确鼻骨新鲜/陈旧骨折患者的SPECT/CT检查影像学资料。观察分析患者鼻骨骨折处CT图像特征,局部断层骨显像及SPECT/CT融合显像的放射性分布、浓聚情况,结合随访鉴别诊断新鲜/陈旧骨折。结果22例患者中7例为新鲜骨折,骨折处放射性浓聚;3例为新鲜骨折和陈旧性骨折并存,部分骨折处放射性浓聚;12例为陈旧性骨折,其中9例骨折处未见放射性浓聚,3例骨折处放射性分布稍增高。结论SPECT/CT融合显像结合随访及CT表现可有效鉴别诊断鼻骨新鲜/陈旧骨折。Objective To explore the application value of fusion imaging of 99TCm-MDP SPECT/CT in judicially identifying the fresh or old nasal bone fracture. Methods The SPECT/CT imaging data of 22 trauma patients, who were not identified suf- fering from the fresh or old of nasal bone fracture by CT, were retrospectively analyzed. We observed and analyzed the images fea- tures of CT of nasal bone fracture, the local layered bone imaging, and the radioactive distribution and concentration situation of fusion imaging of SPECT/CT, and made a differential diagnosis of the fresh or old fracture combined with the follow-up. Results Of those 22 patients, 7 were fresh fracture with radioactive concentration, 3 were fresh and old fracture with partial radioactive concentration, 12 were old fracture, of whom, 9 presented with no radioactive concentration, and 3 with slight higher distribution. Conclusion SPECT/CT fusion imaging combined with follow-up and CT features can effectively make a differential diagnosis of fresh or old nasal bone fracture.
