目的探讨闭合及开放性肺部创伤的多层螺旋CT表现诊断价值。方法对28例肺挫裂伤者进行临床、X线平片、多层螺旋CT扫描,对X线平片及多层螺旋CT片进行对比分析。结果螺旋CT显示肺挫伤21例,裂伤7例,X线平片漏、误诊分别为9例和3例。结论多层螺旋CT能明确肺挫、裂伤的部位、性质、程度,敏感性和特异性高,为临床诊断及治疗提供较X线平片更多的信息及可靠的依据,为肺挫裂伤最重要的检查方法之一。
Objective To investigate the diagnostic value of multi-slice spiral CT in closed and open lung trauma. Methods Twenty - eight cases of pulmonary contusion and laceration were studied by clinical, X - ray plain film and multi - slice spiral CT. The X - ray films and multi - slice spiral CT films were compared. Results Spiral CT showed pulmonary contusion in 21 cases, laceration in 7 cases, X-ray leakage, misdiagnosed as 9 cases and 3 cases respectively. Conclusions Multi-slice spiral CT can identify pulmonary contusion and laceration, and its location, nature, degree, sensitivity and specificity are high. It provides more information and reliable evidence for clinical diagnosis and treatment than lung plain radiography One of the most important tests of injury.
