目的：探讨CT增强薄层扫描图像上显示的异形血管强化征对小肺癌诊断和鉴别诊断的临床价值。方法：用CT增强薄层扫描和常规CT增强扫描对比研究37例直径<3cm的小肺癌，并同期研究18例需鉴别的肺炎性假瘤和肺结核球作对照，分析这3种病变的CT增强薄层扫描征象特点。结果：①CT增强薄层扫描能清晰显示小肺癌病灶内肿瘤血管的特征性表现—异形血管强化征，而常规CT扫描难以显示该征象；②肺炎性假瘤和肺结核球病灶内一般不出现该种病理血管征象。结论：异形血管强化征对小肺癌的诊断和鉴别诊断具有特殊意义。

Objective： The current study was designed to assess the clinical value of heteromorphic enhanced vessel sign in the thin section CT images in diagnosis and distinguished diagnosis for small lung cancer. Methods： A total of 37 distinguished small peripheral lung cancer with less than 3 cm diameter were compared between enhanced thin section CT and conventional enhanced CT. At the same time,18 pulmonary inflammatory pseudotumors and pulmonary tuberculomas required distinguished have been studied as control. The enhanced thin section CT images of the three kinds of diseases were investigated. Results： 1.The enhanced thin section CT scan apparently showed the special signs (heteromorphic enhanced vessel signs) of the tumor vessel in small lung cancer, which was rarely displayed on conventional CT images. 2.The heteromorphic enhanced vessel sign was rarely found in pulmonary inflammatory pseudotumor and pulmonary tuberculoma. Conclusion： The heteromorphic enhanced vessel sign is a valuable CT characteristic for diagnosis and distinguishing diagnosis for small lung carcinoma.
