【中文摘要】:研究不同病理类型肺癌在动态增强CT扫描下的表现及增强特点,并分析不同病理类型肺癌在(18)~F-FDG PET-CT扫描下的SUVmax与其病理类型有无相关性,据此探讨以上两种手段能否作为估计肺癌病理类型的有力补充。材料和方法:研究期间筛选到行动态增强CT扫描的符合条件的患者71例,其中肺鳞癌34例,腺癌25例,小细胞癌9例,大细胞癌2例,类癌1例。因大细胞癌及类癌例数较少,故未进行分析。余68例按病理类型分组,记录病变有无分叶征及毛刺征并统计该征象在不同病理分组中所占比例;平扫及注射对比剂后于30s、60s、90s、120s分别进行扫描并测量CT值,增强后CT值减去平扫CT值为增强幅度,采用单因素方差分析比较组间是否存在差异。行(18)~F-FDG PET-CT检查组,符合条件的患者共45例,按最大径分为三组,≤2cm组,>2cm且≤3cm组及>3cm组,进行单因素方差分析,判断组间是
