目的：探讨多层螺旋CT(MSCT)后处理技术对胸骨细微骨折诊断价值。方法搜集经16层螺旋CT常规胸部容积扫描诊断的胸骨细微骨折69例，利用工作站进行图像后处理，选用多种后处理技术，即多平面重建(MIR)、容积再现法(VR)等重组观察，并与CT横断图像进行比较。结果69例胸骨细微骨折中，横断骨折为48例(占69.6%)，斜行骨折12例(占17.4%)，不全性骨折9例(占13.0%)。矢状位MPR图像对胸骨细微骨折显示率为100%，冠状位显示率为84.1%，横断位显示率为62.3%。结论 MSCT的后处理技术图像可以准确地检出胸骨细微骨折，明显优于横断面图像，尤其是矢状位MPR图像可以避免胸骨细微骨折的漏诊。

Objective To investigate the diagnosis value of multislice spiral CT (MSCT) post-processing technology in sternum subtle fracture. Methods 69 cases of assternum subtle fracture were routinely chest volume scanned by 16-slice spiral CT. After transferring to workstation, post-processing techniques were used to reconstruction and observed with the comparing with cross-sectional, including multi-planar reconstruction (MIR), volume rendering (VR). Results Among 69 cases of sternal subtle fractures, there were 48 cases(69.6%,48/69) of transverse fracture, 12 cases(17.4%,12/69) of oblique fracture, and 9 cases(13.0%,9/69) of incomplete fracture. It indicated that the percentage of sagittal MPR image displaying on the sternum subtle fracture was 100%, cross-sectional displaying rate was 84.1%, and transverse-bit display rate was 62.3%. Conclusion MSCT post-processing image techniques can accurately detect sternal subtle fracture. It was significantly better than the cross-sectional images, particularly sagittal MPR image can avoid misdiagnosis of sternum subtle fracture.
