断层融合技术对鼻骨骨折的诊断价值

The Value of X-ray Digital Tomosynthesis in Diagnosis of Nasal Bone Fractures

目的评价应用冠状位断层融合技术摄片对鼻骨骨折病例的诊断价值。方法对直接鼻骨外伤的病例同摄鼻侧位片及冠状位断层融合技术片，并进行结果对照。结果59例疑似有鼻骨骨折病例鼻侧位片明确诊断24例，占总数40％。冠状位断层融合技术片明确诊断35例，占总数60％。结论冠状位断层融合技术片对鼻骨骨折的影像诊断有较高的实用意义。

Objective To evaluate the value of X-ray digital tomosynthesis in coronal imaging for diagnosis of nasal bone fractures. Methods Both digital radiography in lateral position and tomosynthesis in coronal imaging were performed in 59 cases of nasal bone fractures diagnosed by clinicians and compared the results by the two methods. Results In 59 cases,24 cases were surely seen nasal fractures by digital radiology in lateral position,occupied 40 percent of all,while 35 cases were definitely diagnosed nasal fractures by tomosynthesis in coronal imaging,account for 60 percent of all. Conclusion X-ray digital tomosynthesis in coronal imaging is a useful diagnostic imaging method for nasal bone fractures.
