肺挫伤及肺撕裂伤的X线平片及CT诊断

Laceration of the pulmonary contusion and lung X ray and CT diagnosis of common

目的：提高对肺挫伤及撕裂伤的认识和诊断水平.方法：本文收集了我院2008年1月-2010年10月经CR及CT检查资料较完整的70例胸背部创伤病例.全部病例均行胸部正位或正/斜位拍片及CT检查.CT扫描采用日立Pronto螺旋CT机,以层厚10mm自肺尖至肺底进行螺旋扫描,必要时局部加3-5mm薄层扫描.结果：本组70例胸部外伤病例中,39例有肺实质损伤,其中肺挫伤32例,肺内血肿7例,肺血气囊肿和/或气囊肿5例.结论：肺挫伤影像表现与肺炎相似,一般2-3天可吸收,吸收慢者一至二周可完全吸收;肺血肿或肺血气囊肿影像表现与肿瘤、结核球及肺脓肿、先天性肺囊肿相似,吸收最快者20天,最慢者5个月.

Objective：To improve the understanding of pulmonary contusion and lacerations,and diagnosis. Methods：We collected in our hospital in January 2008 -2010 period of CR and CT examination of 10 more complete information on the back of the 70 eases of thoracic trauma cases. All patients underwent anteroposterior chest or positive / oblique film and CT. Pronto spiral CT scan Hitachi CT machine to thickness of 10mm from the apex to the pulmonary end of the spiral scan, if necessary, additional 3-5mm thin partial scan. Results：The group of 70 patients with chest trauma cases,39 patients with lung parenchymal damage,including 32 cases of pulmonary contusion,hematoma,7 cases of lung,pulmonary blood cysts and / or gas cysts in 5 eases. Conclusion：Image and pneumonia, pulmonary contusion is similar to normal 2- 3 days absorbed slowly absorbed by one to two weeks can be completely absorbed;lung cyst hematoma or blood Image and lung cancer, tuberculoma and abscess, congenital lung cysts similar absorption of the fastest in 20 days,the slowest in 5 months.
