螺旋CT三维重建在鼻骨骨折诊断中的应用

Three-dimensional reconstruction of spiral CT images for the diagnosis of nasal bone fracture

目的探讨螺旋CT三维重建在鼻骨骨折诊断中的准确性和临床应用价值。方法45例鼻骨骨折患者,于螺旋CT扫描后进行三维重建,分析重建影像诊断鼻骨骨折的准确性和优越性。结果在显示鼻骨骨折的类型、位置、范围、碎骨移位等空间信息方面,三维影像明显优于平片和二维影像。结论三维影像能清晰显示鼻骨的空间解剖关系,有较大的临床应用价值。

Objective To evaluate the diagnostic accuracy and clinical feasibility of three-di- mensional construction of spiral CT images for nasal bone fracture. Methods Forty-five cases with nasal bone fracture were included in this study and they were all performed three-dimensional recon- struction with the spiral CT images to explore its diagnostic accuracy and clinical feasibility for nasal bone fracture. Results The 3-D reconstructed images were significantly superior to 2-D and plain film images in demonstrating the space relationships of nasal bone fracture, such as the type, location and extent of fracture, and fragments displacement. Conclusions The 3-D reconstructed images can clearly show more information about the space anatomic relationship of nasal bones and hold more clinical significance for the diagnosis of nasal bone fracture, when combined analysis is made on 2-D and plain film images
