摘要
目的探讨周围型小肺癌的CT征象特点。方法回顾性分析经手术、穿刺或癌检等病理证实的周围型小肺癌患者26例的临床资料，对癌灶内部结构、边缘形态、邻近组织改变及增强后的CT表现进行分析。结果26例患者表现为圆形或类圆形结节16例，不规则结节10例；有分叶24例；空泡征7例；26例进行增强扫描者癌体均有强化，平均强化幅度37HU；细短毛刺或毛刺18例；邻近血管聚集14例；胸膜凹陷10例，邻近胸膜增厚1例。结论螺旋CT扫描特别是靶区HRCT扫描及靶区增强CT扫描可以提高周围型小肺癌的影像学诊断准确率。
Objective To investigate the characteristics of the CT signs of small peripheral lung cancer. Methods The clinical data of 26 patients who were pathologically confirmed to have small peripheral lung cancer by operations,punctuation or cancer examination were retrospectively analyzed. The internal structure of cancer focus, the limbic forms, the changes of adjacent tissues, and the CT manifestations after enhancement were analyzed. Resuits Among the 26 patients,16 patients were manifested as round or similar round nodule,10 patients were manifested as irregular nodule,24 patients were manifested as lobulated, and 7 patients were manifested as vacuole sign. Enhancement of cancer body were observed in all the 26 patients who were examined by enhanced scanning, and the average enhanced range was 37HU; 18 patients had thin and short burrs or burrs, 14 patients had aggregation of adjacent vessels, 10 patients had pleural indentation, and 1 patient had adjacent pleural thickening. Conclusion Spiral CT scanning, especially the HRCT scanning of target areas and the enhanced CT scanning of target areas, can improve the accurate rate of the imaging diagnosis for small peripheral lung cancer.
