周围型肺癌的MSCT影像征象与病理对比分析

Analysis of MSCT imaging features and pathological of peripheral lung cancer

目的探讨周围型肺癌的多层螺旋CT(MSCT)影像征象与组织病理学之间的相关性。方法回顾性分析2015年2月至2016年12月在自贡市第五人民医院经手术病理或细胞学证实为周围型肺癌59例患者的临床资料,对59例患者进行MSCT扫描。结果在周围型肺癌中,不同组织病理类型病灶的发病部位、大小比较,差异均无统计学意义(P>0.05);在分叶征、毛刺征、空泡征CT征象下,不同组织病理类型构成比比较,差异均有统计学意义(P<0.05);不同组织病理类型的平扫CT值、增强60 s后CT值及二者的CT差值比较,差异均无统计学意义(P>0.05)。结论MSCT检查对判断周围型肺癌的组织病理类型有重要意义,掌握其影像征象有助于提高诊断准确率。

Objective To investigate the correlation between MSCT imaging features and histopathology of peripheral lung cancer.Methods Retrospective analysis of59patients with peripheral lung cancer confirmed by surgical pathology or cytology in Zigong Fifth Peple′s Hospital from February2015to December2016,MSCT was performed on59patients.Results In peripheral lung cancer,the site of pathological changes and focus size of different pathological types had no significant difference(P>0.05);in CT imaging signs of the lobulation,thorn,vacuole,the constituent ratio of different pathological types had significant difference(P<0.05);the CT value of plain scan,enhanced60s scan and the difference between them of different pathological types had no significant difference(P>0.05).Conclusion MSCT examination is significance for determining the pathological types of peripheral lung cancer,and mastering its imaging signs is helpful to improve the diagnostic accuracy.
