螺旋CT扫描对周围型肺癌的诊断价值

目的 探讨螺旋CT扫描对周围型肺癌的诊断价值.方法 收集经螺旋CT扫描及病理证实的60例周围型肺癌,其中34例行增强CT扫描,对其CT影像学资料进行分析.结果 周围型肺癌的主要CT征象有:结节状、肿块状、斑片状、分叶征、毛刺征、支气管充气征或空泡征、胸膜凹陷征、血管集束征等.增强CT扫描周围型肺癌呈均匀或不均匀强化,CT值增幅约20～60 Hu,CT值增幅小于20 Hu则提示良性病变如结核球,CT值增幅大于60 Hu考虑炎性病变可能性大.结论 螺旋CT及增强CT扫描对周围型肺癌的诊断及鉴别诊断具有重要价值.

The Diagnostic Value of Spiral CT Scan on Peripheral Lung Cancer

Objectives To study the diagnostic value of spiral CT scan on peripheral lung cancer.Methods 60 cases of Peripheral Lung Cancer that have been underwent Spiral CT Scan and confirmed by pathlogy were collected,and among them,35 cases were performed with enhanced CT scan and their CT images were analyzed.Results The CT signs of Peripheral Lung Cancer are nodules,bump,patchy consolidation,the sub lobe drafts,the burr drafts the vacuole drafts,the bronchial tube gasification drafts,the pleural membrane drafts hollowly and the blood vessel gathers drafts.The results of enhanced CT scan on Peripheral Lung Cancer show homogeneous and non-homogeneous enhancement,and the increase amplitude of CT is about 20-60 Hu.When the increase amplitude is lower than 20Hu,it means benign lesions such as tuberculoma;when the increase amplitude is higher than 60Hu,it probably means inflammatory lesions.Conclusion The Spiral CT Scan and enhanced CT scan are of great significance in diagnosis and the differential-diagnosis.
