摘要

摘要: 目的讨论肺部小结节的良恶性病变的影像表现及鉴别诊断。 材料与方法 搜集经手术证实的肺部小结节病变共17例(直径〈3.0cm〉,男性11例,女性6例,年龄38—83岁,平均63.2岁。采用PQ5000螺旋CT机进行螺旋扫描,7例进行增强扫描,其中5例进行三维重建结果 17例病变中恶性病例12例,良性病例5例,恶性病变中腺癌8例,鳞癌2例,转移癌2例,良性病变中结核3例,炎性结节2例CT征象包括分叶征14例,胸膜凹陷征7例,血管集束征8例,毛刺征14例,密度不均匀者13例。结论 CT扫描对于鉴别肺部良恶性小结节病灶有重要价值。

Abstract: objective To discuss imaging appearance of benign and malignant disease of solitary pulmonary nodule(SPN) and characteristic of diagnosis. Material and Methods 17 patients with pathologically-proved pulmonary nodule (diameter<3.0cm),including males 11cases and females 6 cases with the age of 38-83years (average 63.2 years).using helical CT scan with PQ5000,in them 7cases do contrast CT scans,5 cases do three dimension configuration. Results among 17 cases, malignant disease is 12 cases, benign disease is 5 cases,in malignant disease adenocar-cinoma is 8 cases and squamous-cinoma is 2 cases,in benign disease tuberculosis is 3 cases, inflammation node is 2 cases, the common CT signs included lobulation sign (14 cases),pleural tail sign(7 cases),vessel convergence (8 cases),and spiculation (14 cases),with inhomogeneous (13 cases). Conclusion CT scans about pulmonary nodus have important value in differentiate benign and malignant disease.
