X线及CT在胸部闭合性损伤诊断中作用比较[摘要] 目的：探讨X线与CT在胸部闭合性损伤诊断中的作用特点。方法：回顾性分析本院2006年6月～2010年6月分别应用X线与CT扫描96例胸部闭合性损伤患者的资料。结果：①本组CT检查显示肋骨骨折11例、胸骨骨折1例、锁骨骨折4例，胸椎骨折2例；X线片显示38例肋骨骨折、3例胸骨骨折、5例锁骨骨折，未发现有胸椎骨折病例；②CT检查发现胸部 X线片未检出的单纯血胸14例、单纯气胸8例和血气胸3例；③CT检查较胸部X线片多检出创伤性湿肺4例，肺挫裂伤4例，肺不张 4例，膈肌破裂1例。结论：CT检查是早期诊断肺实质性损伤的重要方法，能为临床医师提供可靠的诊断和治疗依据。 [关键词] CT；肺损伤；闭合性；X线 [中图分类号] R445 [文献标识码] C[文章编号] 1674-4721（2011）07（a）-091-02 Chest X ray and CT in the diagnosis of blunt trauma compared LIAO Xingming, GUO Shaoxian, DAI Ying Department of Radiology, Dongguan City Wangniudun Hospital, Guangdong Province, Dongguan523200, China [Abstract] Objective: To study the chest X ray and CT diagnosis of blunt trauma characteristics. Methods: A retrospective analysis of our hospital from June 2006 to June 2009, respectively, during the application of X ray and CT scan of 96 cases of blunt chest injury data. Results: ①The group of CT examination revealed a rib fracture, 11 cases of fracture of sternum, clavicle fracture in 4 cases, 3 cases of thoracic fractures; X-ray film showed 38 cases of rib fractures, 3 cases of sternal fracture, 5 cases of fracture, not found a thoracic fracture cases; ②CT showed the 5 misdiagnosed cases, CT examination also found that chest X-ray chest were not detected in the pure blood of 14 cases, eight cases of simple pneumothorax, three cases of pneumothorax and blood; ③CT compared with chest X-ray examination detected more traumatic wet lung in 4 cases, 4 cases of pulmonary contusion, atelectasis in 4 cases, 1 case of diaphragmatic rupture. Conclusion: CT examination is substantial damage in the early diagnosis of lung important method for clinicians to provide a reliable basis for the diagnosis and treatment. [Key words] CT; Lung injury; Closed; X ray 胸部闭合性损伤是指胸部遭受撞击、挤压，如暴力挤压、冲撞或钝器打击等引起的钝性伤，胸部在直接或间接暴力作用下，均易发生胸壁及肺实质的损伤。因其类型、程度和病变发展阶段的不同，影像学表现也较为复杂。轻者仅表现为胸壁软组织挫伤或单纯性肋骨骨折，重者多伴有血气胸[1]。本文试通过对2006年6月～2010年6月96例胸部闭合性损伤的CT征象及X线胸片的表现进行分析讨论，以此评价CT在胸部闭合性肺实质损伤检查中的重要性，提高临床治疗率。 1 资料与方
