螺旋CT在隐匿性肋骨骨折诊断中的应用价值分析

目的：探讨螺旋CT及重建技术在隐匿性肋骨骨折诊断中的应用价值。方法：对我院2011年1月至2012年8月收治的37例隐匿性肋骨骨折患者的影像学资料进行回顾性分析。所有患者均进行螺旋CT扫描检查，分析容积再现（VR），最大密度投影（MIP），曲面重建（CPR），多平面重组（MPR）图像对隐匿性骨折的显示能力。结果-37例隐匿性肋骨骨折患者确诊52处骨折，其中，6处（11．54％）位于第l、2肋，33处（63．46％）位于肋骨角，5处（9．62％）位于前肋，8处（15．38％）位于后肋。排除4处，其中3处位于第1、2肋，l处位于肋骨弓部，新增3处，2处位于肋骨角，1处位于后肋。共确诊骨折52处，4处（7．69％）为完全线性骨折，48处（92．31％）为不完全线性骨折。结论：对可疑肋骨骨折患者给予MPR为主，VR定位，CPR重点观察的CT检查方法可以显著提高隐匿性肋骨骨折的检出率与诊断准确性。螺旋CT检查方法图像显示清晰，能满足对隐匿性骨折定位、定性分析的需求。

Application Value Analysis on Spiral CT in the Diagnosis of Occult Fracture of Rib

Objective： To explore application value on spiral CT and reconstruction technology in occult fractures of the ribs diagnosis Method：In our hospital, from Jan. 2011 to Aug. 2012, 37 cases of occult fractures of the ribs patients with imaging data were retrospectively analyzed. All patients were examined by spiral CT scan. volume （VR）, maximum intensity projectioJ. （MIP） , surface reconstruction（CPR） , multi- planar reconstruction （ MPR） images were all analysed to be found the display capability to occult fracture. 4 Result： 37 cases of occult fracture of rib fracture patients were diagnosed in 52 sites, among them, 6 sites （ 11.54% ） were located at first, second rib, 33 （63.46% ） were located in the angle of the ribs, 5 sites 19.62% ） were located in the anterior rib, 8 sites （15.38%） were located in the posterior rib. Exclude 4 sites, of which 3 siteswas located at first, 1 at the 2 rib, rib arch, added 3, 2 at the angle of the ribs, 1 was located in the posterior rib. A total of 52 confirmed fracture, 4 sites （ 7.69% ） for the complete linear frac- ture, 48 sites （92.31% ） for the complete linear fracture. Conclusion： The suspicious rib fracture patients are given MPR, VR, CPR on CT examination method so that the detection rate of occult fractures of the ribs and the diagnostic accuracy can be significantly improved . It can meet the needs for occult fracture positio- ning, qualitative analysis of demand that spiral CT examination method, clear image is displayed.
