目的 探讨CT扫描在分析大叶性 肺炎治疗效果中的临床诊断价值。方法 回顾性分析我院2014年1月-2016年1月期 间接收确诊并治疗的67例大叶性肺炎患者 的CT检查资料，分析不同时期大叶性肺炎 的的CT影像特征。结果 本组67例患者仅7 例为双肺均受累，占10.4%。又以右肺为 主有45例，左肺共29例。67例患者中14例 处在渗出期，48例处在实变期，还有5例 处在消散期。9名患者在一周内可见高密 度阴影的明显缩小，52例患者在2周后的 高密度阴影缩小达到70%以上，56例患者 在第3周高密度阴影基本消失，4周后所有 患者均显示高密度阴影消。结论 利用CT 扫描检查大叶性肺炎时可以发现病变部位 以及阶段对治疗起到很好的指导作用，在 患者治疗阶段根据CT影像特征能很好的确 定患者治疗情况，对后期病情的针对性治 疗可以起到很好的指导性作用，值得进一 步推广和应用。

Objective To investigate the clinical value of CT in the therapy of lobar pneumonia. Methods Retrospective analysis of CT data of 67 patients with lobar pneumonia in our hospital from January 2014 to January 2016. And comprehensive analysis of the CT imaging features. Results Among 67 patients, only 7 cases (10.4%) are double lung involved, 45 cases of right lung mostly involved, the right lung has 29 cases. There were 14 cases in the stage of exudation, 48 cases in the period of change, and 5 cases in dissipation period. The visible shadow with high density of 9 cases was significantly reduced within a week, shadow with high density of 52 patients was reduced to 70% after 2 weeks, the high density shadow of 56 patients disappeared after the 3 week, and high density shadow of 4 cases eliminated after 4 weeks. Conclusion The use of CT scanning can ascertain the lesion type of lobar pneumonia and determine the location and size of lesions, and utilize to the characteristics of CT scanning image to understand the stage of lobar pneumonia. It has significance clinical value in localization and qualitative of lobar pneumonia, displaying a very good role in guiding the condition treatment, which is worthy of further promotion and application.
