目的探讨血管集中征对周围型肺癌的诊断与鉴别诊断价值。方法对69例周围型肺癌和20例其他孤立肺结节行团注增强薄层CT扫描,对血管集中征与周围型肺癌CT表现的病理基础、不同组织学类型及鉴别诊断进行了讨论。结果周围型肺癌的血管集中征发生率为67%(46/69)比其他孤立肺结节(10%,2/20)高。结论血管集中征对周围型肺癌诊断与鉴别诊断很有帮助。
Objective To investigate the value of vascular centralization in the diagnosis and differential diagnosis of peripheral lung cancer. Methods Thirty-nine cases of peripheral lung cancer and 20 cases of solitary pulmonary nodules were enrolled in this study. Thin-section CT scanning was performed to investigate the pathological basis, histological types and differential diagnosis of CT findings of peripheral and central lung cancer. Results The incidence of peripheral blood vessels was 67% (46/69) higher than that of other isolated pulmonary nodules (10%, 2/20). Conclusion Vascular focus on peripheral lung cancer diagnosis and differential diagnosis is very helpful.
