【摘要】目的探讨X线和CT对胸部外伤的诊断价值。方法回顾性对照分析胸部外伤患者的X线平片及CT表现。结果胸部骨折共检测出胸部骨折150例，X线检测出135例，CT检测出142例；肺挫伤80例，X线检测出35例，CT检测出80例；肺撕裂伤33例，其中X线检测出15例，CT检测出33例；血胸、气胸以及血气胸共78例；其中X线检测出50例，CT检测出78例；肺不张10例，其中X线平片检测出2例，CT检测出10例；纵膈气肿37例，其中X线平片检测出21例，CT检测出37例；皮下气肿28例，X线平片检测出17例，CT检测出28例。结论X线平片是胸部外伤的首选的检查方法，CT检查在明确病变的部位、性质以及程度方面要优于X线平片的检查。

【Abstract】ObjectiveTo study the diagnostic value of X-ray and CT of chest trauma.Methods X-ray and CT data of 156 cases of chest trauma were analyzed and reviewed.ResultsThe fracture were showde by X-ray in 135 cases and by CT scan in 142 cases, in 150 cases of chest fracture; in 80 cases of lung injury, the fracture were showde by X-ray in 35 cases and by CT scan in 80 cases; in 33 cases of lung laceration, the fracture were showde by X-ray in 15 cases and by CT scan in 33 cases; in 78 cases of hemothorax, pneumothorax and hemopnemothorax, the fracture were showde by X-ray in 50 cases and by CT scan in 78 cases; in 10 cases of pulmonary atelectasis, the fracture were showde by X-ray in 2 cases and by CT scan in 10 cases; in 37 cases mediastinum pneumothorax, the fracture were showde by X-ray in 21 cases and by CT scan in 37 cases; in 28 cases subcutaneouly pneumothorax, the fracture were showde by X-ray in 17 cases and by CT scan in 28 cases. ConclusionX-ray is the first choice to examine chest trauma.But CT is considered better than X-ray on the position, character and level of the disease.

随着社会的不断发展，人民生活水平的不断提高，交通事故等意外伤害所致的胸部外伤逐渐增加。胸部外伤在急症外科中是常见病、多发病，由于胸部包含有心、肺等重要脏器，则常并有严重的复合伤存在，死亡率较高，大约占所有胸部外伤的25%[1,2]。因此，合理的选择检查方法对急诊外科医生来说尤为重要。我们对比分析了我院2009年2月至2010年5月间156例胸部外伤患者的X线平片和CT检查结果，探讨其影像学价值，以进一步提高影像学检查的准确率，为临床诊断提供可靠的理论依据。
1资料与方法
1.1一般资料本院2009年2月至2010年5月间因胸部外伤进行X线平片和CT检查的156例病例，其中男性102例，女性54例，年龄在15-72岁之间，以青壮年为主。致伤原因交通事故121例，刀刺伤10例，高空坠落伤11例，砸伤9例，其他5例。
1.2临床表现咳嗽、胸痛、气短、进行性呼吸困难，有的患者可出现咯血表现。如果合并有复合伤时，常出现紫绀、发热、昏迷甚至休克等临床表现 ......
