摘　　要：目的：探讨多层螺旋CT（MsCT）后处理技术显示周围性肺癌与支气管关系并分析其影像表现及其相关价值。方法：对38例周围性肺癌患者采用MSCT行层厚为1．0mm的容积靶扫描，通过多层面或曲面重建（MPRorCM—RP）以及表面遮盖显示（SSD）的方法，显示支气管与外周肺癌的关系。将结果与手术标本、病理切片对照。全部3～7级支气管均全程清晰、完整的显示，肿瘤与支气管有关系者：21例腺癌中18例（85．7％），11例鳞癌中8例（75．0％）。其他4例。肿瘤一支气管关系分为4型：I型：支气管被肿瘤截断；Ⅱ型：支气管进入肿瘤内部被截断；Ⅲ型：支气管在肿瘤内保持通畅；VI型：支气管紧贴肿瘤边缘走行，形态正常或受压移位。其中I型发生率为47．4％（18／38），其中鳞癌略多于腺癌；Ⅱ型发生率为15．8％（6／38），其中鳞癌略多于腺癌；Ⅲ型发生率为15．8％（6／38），仅见腺癌；IV型为21％（8／38）腺癌略多于鳞癌。与第4级支气管相关的肿瘤，鳞癌多于腺癌；与第6级支气管相关的肿瘤，腺癌多于鳞癌。结论：采用MSCT，超薄层靶扫描后行MPR、CMPR和SSD重建能准确地显示肿瘤与支气管关系，反映一定的病理改变，为后续良恶性鉴别或长期预后等相关性研究打下基础。Objective： Investigate the association of peripheral lung carcinoma with bronchia, demonstrated by multi- slice CT （MSCT） post--processing technique, and analyse its imaging findings and relevant values. Method： The volu- metric targeted scan of 1.0--mm thickness with MSCT were conducted in 38 patients with peripheral lung carcinoma, to demonstrate the association of pheripheral lung carcinoma with bronchia through multiplayer reforming （MPR） or curved multiplanner reconstruction （CMRP） as well as shaded surface display methods. The results were compared with surgical specimens and pathological sections. Results： All 3 - 7- level bronehia were shown clearly and completely through the whole course, and the association of carcinoma with bronchia was demonstrated in： 18 （85.7%） out of 21 patients with adenocarcinoma, and 8 （75.0%） out of 11 patients with squamous carcinoma. The association of carcinoma with bronchia included 4 types.. Type I, the bronchia were obstructed by the tumor; Type II, the bronchia were obstructed in the tumor; Type IfI, the bronchia were not obstructed in the tumor; Type VI, the bronchia passed next to the margin of the tumor, with normal topography or with compression and displacement. The incidence of Type I was 47.4% （18/38）, of which the patients with squamous carcinoma were more than those with adenocarcinoma; that of Type II was 15.8% （6/ 38）, of which the patients with squamous carcinoma were slightly more than those with adenocarcinoma; that of Type III was 15.8% （6/38）, of which the patients were only with adenocarcinoma; and that of Type IV was 21% （8/38）, of which the patients with adenocarcinoma were slightly more than those with squamous carcinoma. Of tumors associated with Level 4 brochia, the patients with squamous carcinoma were more than those with adenocarcinoma; and of tumors associated with Level 6, the patients with adenocarcinoma were more than those with squamous carcinoma. Conclusion： The association of tumor with bronchi
