摘要
目的：探讨螺旋CT（SCT）多模式三维重建（MM3DR）诊断复杂性骨盆骨折的应用价值。方法：128例均摄骨盆C线片；同时采用3—5mm层厚连续SCT扫描，1．5～2．5mm间距后重建，源像传于AW4．0工作站行SSD、MPR及MIP三维重建；采用SSPS13．0软件分析。结果：SCTMM3DR与X线片对复杂性骨盆骨折诊断率差异有统计学意义（P〈0．01）；SSD与MIP能对复杂骨盆骨折获取清晰全景立体图像，MPR能多角度观察骨盆各骨骨折的细节情况。结论：MM3DR对复杂骨盆骨折诊断、分型与手术选择等有重要参考价值。
Objective ：To explore clinical application of multi -mode 3D reconstruction （MM3DR）by using spiral CT（SCT） in diagnosis of complex pelvic fractures. Methods ：One hundred and twenty eight cases with pelvic fractures accepted X -ray test and continuous SCT with thickness of 3 -5mm in each slice, 1.5 - 2.5mm between consecutive two slices. The original images were uploaded to AW 4.0 workstation and then were reconstructed to be SSD （ surface shadow display） , MIP （ Maximum Intensity Project） and MPR （ Multiplanar reformation）. These data were analyzed by the software of SSPS13.0. Results：There was significant difference in diagnosis as pelvic fracture by 3DSCT and X - ray test （ χ^2 = 35. 758 ,P 〈 0.01 ）. SSD and MIP could display the full view of stereopicture of complex pelvic fracture. The details of pelvic fracture can be observed on MPR. Conclusions ：MM3DR has important values for diagnosis, classification and surgical setected of complex pelvic fracture.
