目的探讨螺旋CT在周围型小肺癌中的诊断价值。方法回顾分析40例患者的临床资料。结果本组40例周围型小肺癌表现为结节状、不规则状、分叶状肿块,周围有细小毛刺、血管集束征、毛玻璃征和胸膜凹陷征产生,肿瘤内部可见空泡征、细支气管充气征、小空洞及钙化。CT增强扫描后出现明显强化,均匀强化和不均匀强化都有表现。结论熟悉并掌握上述征象是提高周围型小肺癌早期诊断率的关键。螺旋CT薄层扫描或增强扫描对周围型小肺癌的诊断与鉴别具有重要意义。
Objective To investigate the diagnostic value of spiral CT in peripheral small lung cancer. Methods The clinical data of 40 patients were retrospectively analyzed. Results The group of 40 cases of peripheral small lung cancer showed nodular, irregular, lobulated tumor, surrounded by small burr, vascular bundling sign, frog glass sign and pleural indentation, visible within the vacuolar vacuoles, bronchioles Inflatable sign, a small hole and calcification. CT enhanced scan significantly enhanced, uniform and uneven enhancement have performance. Conclusion It is the key to improve the early diagnosis rate of small peripheral lung cancer by familiarizing with the above signs. Spiral CT thin layer scan or enhanced scan of peripheral small lung cancer diagnosis and identification is of great significance.
