目的探讨CT图像不同后处理技术的组合方式在肋骨微细骨折诊断中的价值.方法对98例多层螺旋CT (multislice spiral CT,MSCT)检查显示细微骨折的患者进行观察.分别用(A)容积再现(volume rendering, VR)+曲面重组(curved planar reformation, CPR)+轴位;(B)最大强度投影(maximum intensity projection, MIP)+CPR+轴位及(C)VR+MIP+CPR+轴位3种不同图像组合方式观察.结果 98例患者,显示肋骨细微骨折265处.采用VR+MIP+CPR+轴位(四步观察法)的C组资料,肋骨微细骨折的检出率分别高于A组( χ~2＝6.67,P＜0.01)和B组(χ~2＝6.75,P＜0.01). 结论 MSCT"四步观察法"能提高肋骨微细骨折的检出率,有较高的临床价值.

Objective To approach the value of combination mode of different CT post-processing technique in diagnosing rib fine fracture.Methods 98 patients suspected with rib fractures underwent multislice spiral CT(MSCT) scanning,and CT features of rib fractures were observed with the combination of three different images:(A)volume rendering(VR),curved planar reformation(CPR) and axial view;(B)maximum intensity projection(MIP),CPR and sxial view;and(C) VR+MIP,CPR and axial view.The results were respectively recorded.Results 265 rib fine fractures were found among 98 patients.The detecting rate of fine fractures with C group was higher than that with A group (χ~2＝6.67,P＜0.01) and B group (χ~2＝6.75,P＜0.01).Conclusion MSCT four step observation method can improve the detecting rate of rib fine fracture,that is of important clinical value.
