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临床应用价值。方法选取肋骨隐匿性骨折疑似患者90例，经数字X线摄影均未见明显骨折征象，对其实施多层螺旋CT检查，分别采用容积再现（VR）、曲面重建（CPR）、多平面重建（MRP）、最大密度投影（MIP）四种方法进行图像重建，对其诊断结果进行回顾性分析。结果90例患者经多层螺旋CT图像重建后，共计发现肋骨骨折132处，包括16处完全线性骨折，116处不完全性骨折（42处外源性骨折和74处内源性骨折）；四种图像重建方法中，以CPR（100.00%）、MPR（93.18%）对于肋骨隐匿性骨折的诊断准确率最为显著，明显高于VR（78.79%）、MIP（36.36%），差异有统计学意义（P〈0.05）。结论采用多层螺旋CT对肋骨隐匿性骨折进行诊断，可清晰反映患者肋骨空间结构，实现多角度、多方位观察，同时结合CPR、MPR对扫描影像进行三维重建，可进一步提高患者肋骨影像的清晰度及完备性，有助于明确早期肋骨隐匿性骨折，对于临床治疗方案的制定具有十分积极的意义。
Objective To investigate the clinical application value of three-dimensional reconstruction of multi-slice spiral CT in the diagnosis of occult fracture of rib. Methods Ninety cases of patients suspected with ribs occult fracture were selected, all patients had no obvious sign of fracture by digital radiography, and they were given the multi-slice spiral CT examination. Volume rendering （VR）, surface reconstruction （CPR）, multi planar reconstruction （MRP） and maximum intensity projection （MIP） were used for image reconstruction, respectively. The diagnostic results were retrospectively analyzed. Results In this study,, a total of 132 fractures of the ribs were found in 90 patients, including 16 complete linear fractures, 116 incomplete fractures （42 exogenous fractures and 74 endogenous fractures）. Among the four kinds of image reconstruction methods, the accuracy of CPR （100%） and MPR （93.18%） for the diagnosis of occult rib fractures was significantly higher than that of VR （78.79%） and MIP （36. 36% ）, the differences were statistically significant （P 〈 0. 05 ）. Conclusions Multi-slice spiral CT can be used to diagnose occult fracture of ribs, which can clearly reflect the spatial structure of the ribs of patients and realize the multi-angle and multi-orientation observation. Meanwhile, CT combined with CPR and MPR can reconstruct the three-dimensional images, further improve the articulation and completeness of rib images, conduce to clear the early ribs occult fracture, and has a very positive significance in the development of clinical treatment program.
