【摘要】 目的 探讨汶川大地震伤员胸部外伤的影像学表现特点。 方法 对2008年5月12日-6月21日因地震胸部外伤在我院放射科检查的687例患者（年龄1～96岁）的临床资料进行回顾性分析。将患者按10岁为一个年龄组划分。所有患者均行胸部X线片检查，38例行CT检查。 结果 687例患者中，256例检查结果为阳性，阳性率为37.26%。年龄以30~79岁年龄组为主。在阳性伤员中，98例（38.28%）为多系统多发伤，159例（62.11%）为多种类型胸部伤同时存在，肋骨骨折198例（约77.34%），肺挫裂伤49例(约19.14%)。 结论 本组地震伤员多系统多发伤、多类型胸部伤常见，肋骨骨折及肺挫裂伤为主要损伤表现。影像学检查有助于胸部外伤的及时和准确诊断。【Abstract】 Objective To explore the imaging features of thoracic trauma in patients injured in Wenchuan earthquake. Methods The radiological data of 687 patients (aged from 1 to 96 years) with thoracic trauma who underwent radiological examinations between 12 May and 21 June 2008 were retrospectively analyzed. The patients were divided into subgroups according to the age. All patients underwent X-ray plain film examination, in whom 38 underwent CT examination. Results In 687 patients, the results of the examination were positive in 256 with a positive rate of 37.26%; the major injured patients were in the 30-79 years old group. In the patients with positive findings, 98 (38.28%) were accompanied by multi-system injuries, 159 (62.11%) were comprised of several types of thoracic trauma. There were 198 patients (about 77.34%) with rib fracture and 49 patients (19.14%) with lung contusion. Conclusions Multi-system injuries and several types of thoracic trauma are common in the patients injured in the earchquake. The main traumatic manifestations are rib facture and lung contusion. Imaging examination is very helpful in the diagnosis of thoracic trauma.
