【摘要】：目的探讨多层螺旋CT三维重建技术在肋骨隐匿性骨折诊断中的应用价值。方法对45例临床怀疑肋骨骨折,而数字X线摄影(DR)检查未见骨折征象的病例,行多层螺旋CT扫描,并以最大密度投影(MIP)、多平面重建(MPR)、曲面重建(CPR)和容积再现(VR)4种图像处理方法重建,分析各方法诊断准确率。结果 45例患者共检出肋骨隐匿性骨折66处,以不完全性骨折为主(87.88%),多位于肋骨角处(59.09%)。4种三维重建技术中以CPR检出率最高(100%),其次为MPR(96.97%)、VR(78.79%),MIP最低(31.82%)。各方法总检出率比较,差异有显著性意义(χ2=110.41,P0.01),其中CPR总检出率明显高于VR、MIP(P均0.01)。结论多层螺旋CT三维重建技术能直观、准确、高效地显示肋骨隐匿性骨折,具有较高的诊断价值和应用前景。
[Abstract]:Objective to investigate the multi-slice spiral CT in diagnosis of occult rib fractures. Methods 45 cases of clinically suspected rib fractures, and digital radiography (DR) examination showed no signs of fracture cases underwent multi-slice spiral CT scanning, and the maximum intensity projection (MIP), multi planar reconstruction (MPR). Surface reconstruction (CPR) and volume rendering (VR) reconstruction of 4 kinds of image processing methods, analysis of the accuracy rate of diagnosis method. The results were detected in 45 patients of occult rib fracture 66, with incomplete fractures (87.88%), located in the corner of the rib (59.09%).4 three-dimensional reconstruction technique in CPR the highest detection rate (100%), followed by MPR (96.97%), VR (78.79%), MIP (31.82%). The lowest total detection rate compared with significant difference (2=110.41, P0.01), the total detection rate of CPR was significantly higher than that of VR, MIP (P 0.01). Conclusion the technique of 3D reconstruction multi slice CT can direct The view, accurate and efficient display of the occult fracture of the ribs has a high diagnostic value and application prospect.
