摘　　要：目的 探讨胸部闭合性肺挫伤的CT表现及其诊断、随访价值.方法 回顾性分析56例肺挫伤病例的临床及影像学资料.结果 X 线检查23例,发现肺挫伤18例,5例为阴性；CT发现56例肺挫伤涉及右肺13例,左肺8例,两肺均受累35例,共计135叶肺叶受累,CT表现可分为3型,即间质型肺挫伤13例（23.2％）,实质型肺挫伤31例（55.4％）,混合型肺挫伤12例（21.4％）,治疗后复查间质型肺挫伤1～3d病灶均完全吸收,实质型和混合型肺挫伤1周后病灶开始吸收,3周后病灶基本吸收,6例遗留纤维化病灶和胸膜粘连肥厚改变.结论 CT能早期诊断肺挫伤、了解其严重程度而且是动态追踪复查肺挫伤的最佳影像学方法,其CT分型对临床病情、病程判断有重要的指导价值.Objective To investigate CT findings and diagnosis,follow-up value in the chest closed pulmonary contusion.Methods The clinical and imaging data of 56 patients with pulmonary contusion were retrospectively analyzed.Results 23caseswithX-raycheck,18caseswerefoundpulmonarycontusion,and five cases were negative.CT found 56 cases of pulmonary contusion involving 13 cases of the right lung,8 cases of the left lung,35 cases of both lungs involved,a total of 135 lung lobes involvement.CT performance can be divided into three types,interstitial pulmonary contusion in 13 cases（23.2％）,the substance of the pulmonary contusion in 31 cases（55.4％）,the mixed pulmonary contusion in 12 patients （21.4％）.After treatment,interstitial pulmonary contusion lesions were completely absorbed after 1 ～ 3 days,lesions began to absorb in the substance and mixed pulmonary contusion after 1 week and absorbed completely 3 weeks after treatment.Six cases left over from fibrosis lesions and pleural adhesions hypertrophic changes.Conclusion CT is helpful for early diagnosis of pulmonary contusion,it is the best imaging method in understanding its severity and dynamic track review of pulmonary contusion,the CT classification has important guiding value in clinical conditions and duration judgment.
