摘要:
<b<目的</b< 讨论肺部小结节的良恶性病变的影像表现及鉴别诊断。 <b<材料与方法</b< 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 <b<结果</b< 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。 <b<结论</b< CT扫描对于鉴别肺部良恶性小结节病灶有重要价值。
Abstract:
<b<objective</b< To discuss imaging appearance of benign and malignant disease of solitary pulmonary nodule(SPN) and characteristic of diagnosis. <b<Material and Methods</b< 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. <b<Results</b< 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). <b<Conclusion</b< CT scans about pulmonary nodus have important value in differentiate benign and malignant disease.
