摘要
目的:评价螺旋CT三维重建技术在骨骼系统疾病中的临床应用价值。材料与方法:对100例骨骼系统疾病的病人行螺旋CT扫描,X线准直宽度为1.0mm^4.0mm,重建间隔为0.5mm^2.0mm,螺距比为1.25~1.50。将原始数据传入工作站,分别用表面遮盖显示法(surface shaded display,SSD)和容积成像(volumetric redering,VR)及多平面重建成像(multiplane reconstructions,MPR)进行处理。结果:所有病例的三维重建图像显示良好,病变显示立体、直观、全面。结论:螺旋CT三维重建图像具有立体、直观、完整、准确的特点,能够对骨骼系统疾病的诊断提供全面的临床信息,对术后复位效果的观察具有重要价值。
Purpose： To evaluate tile clinical usefulness of three - dimensional reconstruction with helical CT （3DCT） in the diseases of skeletal system. Materials and Methods： 100 patients with diseases of skeletal system were scanned by helical CT and collimator was 1.0 - 4.0mm, reconstruction interval 0.5 - 2.0mm and pitch 1.25 - 1.50. All data were transferred to workstation and processed with surface shaded display （SSD）, lnuhiplane reconstructions （MPR） and volumetric rendering （VR）. Results： All 3DCT images can display the lesions accurately and stereoscopically. Conclusion： 3DCT images have merits of accuracy and stereoscopy, and provide full information in preoperative diagnosis and have an intportant role in assessing the effect of replacement after operation.
