低剂量螺旋CT扫描在胸部外伤检查中的应用

目的 对低剂量螺旋CT扫描在胸外伤检仓中的应用进行探讨分析。方法选取2011年6月-2012年2月期间，该院收治的16例胸外伤患者，对其进行常规x线胸片和胸部低剂量螺旋CT扫描，并对两种检查方式进行比较分析。结果经常规X线胸片柃查，14例没有现异常，2例患行提示为右下肺局部有肺挫裂伤阴影。然而经低剂量螺旋CT扣描提示，10例患者无异常，6例患者肺局部有挫裂伤，且呈片状模糊影。x线片检查正侧左右斜位平均耗时为14．8min：而低剂量螺旋CT胸部扫描在20s内完成．结论任对胸外伤患者进行榆在及诊断中，胸部低剂赞螺旋cT具有重要的价值和积极的意义，值得临床椎广应用。

Objective To analysis and investigate the application of thorax low dnsespiral CT in diagnosing of thorax trauma. Methods Selected 16 thorax trauma caseswho were treat in our hospital between Jun,2011 and Fer,2012. Diagnosed them by using routine X-ray thorax plain film and thorax low dose spiral CT scanning. Then compare the effect of the two methods. Results By using routine X-ray thorax plain film, it showed 14 eases were nornml, and 2 cases were f＇ound local shadow of lung contusion. By using thorax low dnse spiral CT scanning, it showed 10 eases werenornml, and 6 cases were found local shadow of lung rending. X-ray examination is about the inclined a took an average of 14.8 minutes. And low dose spiral CT scan chest in 20 seconds. Conclusion It is important and valuable to use thorax low dose spiral CT scanning in diagnosing of thorax trauma.
