利用放射性核素骨显像检查鉴别鼻部骨折新旧程度回顾性法医学分析

目的 利用放射性核素骨显像检查鉴别鼻部骨折的新旧程度.方法 对48例疑似陈旧性鼻部骨折伤者放射性核素全身骨显像、局部断层骨显像及CT融合图像在鼻部骨折处放射性分布、浓聚情况的分析,鉴别鼻部骨折的新旧程度.结果 48例中8例放射性核素全身骨显像、局部断层骨显像及CT融合图像在鼻部骨折处显示放射性分布增高、浓聚区,诊为新鲜骨折,评定为轻伤;40例在鼻部骨折处未见明显异常放射性分布增高、浓聚区,诊为陈旧骨折,与本次外伤无因果关系.结论 放射性核素骨显像检查在鉴别鼻部骨折新旧程度方面可得到满意结果.

A study on use of radionuclide bone imaging for deciding new or old of nasal bone fracture

Objective To explore the utilization of Radionuclide bone imaging for identifying new or old of nasal bone frae ture. Methods Based on whole body radionuclide bone scan, bone CT and fusion imaging, 48 eases of nasal bone fracture had been studied on the distribution of radioactive and concentrating situation to decide new or old of nasal bone fracture. Results All the/18 cases of nasal }）one fracture showed distribution of radioactive. Eight of them were assessed as minor injuried, which showed higher distribution of radioactive and were diagnosed as fresh fracture; forty did not showed higher distribution of radioactive and were diagnosed as old fracture which were supposed to have nothing with the trauma. Conclusion Whole body Radionuclide bone scan, bone CT and fusion imaging have a great value in deciding new or old of nasal bone fracture in forensic medical practice.
