摘　　要：①目的　分析周围型肺腺癌的CT征象特点以提高CT诊断正确率。②方法　对经手术与病理证实的 6 7例周围型肺腺癌病人的术前CT征象进行回顾性分析。③结果　周围型肺腺癌内部呈空泡征或支气管充气征 31例 (40 .3% ) ,其中 2 6例为中高分化的腺癌。病灶 肺界面呈毛刺征 37例 (5 5 .2 % ) ,深分叶征 38例 (5 6 .7% ) ,棘突征 4 7例 (70 .1% )。病灶邻近结构出现胸膜凹陷征 4 0例 (5 9.7% ) ,血管集中征 39例 (5 8.2 % )。 5 4例(80 .6 % )出现上述 3种以上征象。Objective To analyze the CT features of peripheral lung adenocarcinomas so as to improve the accuracy of the diagnosis. Methods The CT features of 67 patients with peripheral lung adenocarcinomas proved by operation and pathology were studied retrospectively. Results The basic CT features were as follows: vacuole or air bronchus-charging sign was found in 31 cases (40.3%), in which, 26 were moderately and highly differentiated; spiculation sign in 37 (55.2%); deep lobulation sign in 38 (56.7%); spiculate protuberance sign, 47 cases(70.1%); pleural indentation sign, 40 (59.7%); vessel convergence sign in 39 (58.2%); 54 cases had more than three basic CT signs mentioned above.
