摘要
目的:通过比较螺旋CT二维图像(薄层横断面与多平面重建MPR)与三维图像(SSD)诊断颌面骨骨折的准确性,探讨三维图像的临床应用价值。材料与方法:对28例颌面骨骨折患者行螺旋CT薄层横断面扫描、MPR及表面遮盖法三维重建(SSD)。结果:螺旋CT三维图像对于显示骨折的位置、类型、范围、不规则骨折线的走行及骨折块移位的情况可提供更多信息。二维图像对于显示细微骨折及深部骨折优于三维图像。结论:二维图像是诊断颌面骨骨折的基础,三维图像可较为直观的显示骨折的全貌及空间位置关系,有较大的临床价值。二者结合是颌面骨骨折的最佳检查方法。
Objective:To compare the diagnostic accuracy of 3D(SSD) spiral CT images with 2 D(axial and MPR)images in facial fracture and to assess the clinical values of three dimensional images.Materials and Methods:Twenty eight cases of facial fractures were examined with spiral CT and performed MPR,SSD reconstruction in work station.Results:3D(SSD) images provided superior definition of the fracture type,location,extent,fracture displacement,especially the courses of fracture line.2D images were more accurate in define tiny fractures and fractures of deep structures.Conclusions:2D images are still the most accurate and basic method for facial fractures.3D images have more advantages in demonstrating space relationships of facial fractures so it has higher clinical value than 2D images.Combination of 2D and 3D image is the best method for facial fractures.
