16层螺旋CT重建在距骨骨折的应用价值

目的:研究16层螺旋CT多平面(MPR)、三维(3D)重建在距骨骨折中的临床应用价值。资料与方法:对132例距骨骨折患者的X射线平片、16层螺旋CT-MPR、3D重建影像资料对比分析。结果:132例距骨骨折中,16层螺旋CT-MPR、3D重建骨折和脱位全部显示,X射线平片查出骨折99例,脱位31例。骨折X射线平片检出率75%,三维重建检查检出率100%,脱位X射线平片检出率87%,三维重建检查检出率100%。结论:16层螺旋CT多平面和三维重建,可更好地显示距骨骨折和脱位,对术前诊断和治疗有很大价值,尤其是对距骨细微骨折和半脱位的诊断。

The Diagnostic Value of 16-Slice Spiral CT Reconstruction in Talus Fractures

Objective： To study the clinical application of 16-slice spiral CT＇s multiplauar reconstruction （MPR） and three Dimension （3D） reconstruction images in evaluation of talus fractures. Materials and Methods： A retrospective analysis was done for 132 cases of talus fractures who received both the X-ray examination and the 16-slice spiral CT examination. Their plain films, 2D trans-axial images and 3D reconstruction images of 16-slice spiral CT examination were compared and analyzed. Results： MPR and 3D images showed all of the fractures and dislocation in 132 cases. X-ray plain films showed 99 cases of fractures and 31cases of dislocation, which their detecting rate was 75% and 87% respectively. Conclusion： 16-slice spiral CT images with MPR and 3D reconstruction can provide more valuable information for the clinical diagnosis and therapy of talus fractures and dislocation.
