80例周围型肺癌的CT征象及临床意义

Symptom and Clinical Value of CT in 80 Patients with Peripheral Lung Carcinoma

目的:探讨螺旋CT在周围型肺癌诊断中的临床应用价值。方法:手术和(或)病理证实的周围型肺癌80例,行常规肺部CT扫描检查,并在病灶处用增强CT扫描并进行分析。结果:80例周围型肺癌患者CT图像以分叶征52例(65%)、毛刺征51例(63.75%)、胸膜凹陷48例(60%)、血管集束征14例(17.5%)占主要征象。增强扫描瘤体均有强化。结论:CT影像检查发现肺内结节或肿块,分叶征、毛刺征合并上述其他一项以上征象出现时提示周围型肺癌的可能性大,CT扫描在诊断周围型肺癌具有较高的临床价值。

Objective： To evaluate the diagnostic value of CT in patients with peripheral lung carcinoma. Methods： Routine CT scanning was performed in 80 cases of peripheral lung carcinoma confirmed by surgery and/or pathology. Thin slice scanning of the lesion with high-resolution reconstruction was done when a lesion was found in CT scanning. Results ： CT scanning showed that lob- ulation sign was found in 52 cases （65 ~~）, spiculation sign in 51 cases （63.75~）, pleural indentation in 30 cases （60~）, blood ves- sel cluster in 14 cases （17.5 ~//00）. All symptom were strengthened when enhanced CT scanned the lesion. Conclusion：The coexis- tence o~ lobulation sign and spiculation sign associated with any sign as mentioned above suggest it is likely SPLC. CT scanning showed a high value in diagnose of peripheral lung carcinoma.
