肺内孤立结节周边结构CT征象对良、恶性病变的诊断价值初步分析

目的:统计分析孤立性肺结节周边结构CT征象对良、恶性病变的诊断价值。方法:收集143例经病理证实的孤立肺结节病例,行常规和对病灶局部薄层扫描,按照良、恶性进行分组,对良、恶性肺结节周边征象进行分类统计,包括分叶征、血管切迹征、棘突征、毛刺征、边缘锐利、胸膜凹陷征、血管集束征、阳性支气管征、晕征、卫星灶征、充血征、引流线征等12个邻近肺野征象。比较不同征象在良、恶性结节中出现的百分比是否有统计学差异。结果:143例病例中,良性病变44例,恶性病变99例,除阳性支气管征和绒毛征外,其他周边结构征象在良、恶性肺结节中差异均显著(P<0.05)或非常显著(P<0.01)。结论:绝大多数孤立性肺结节的周边征象对诊断有价值。阳性支气管征和绒毛征在良、恶性结节中相差不大。

Diagnostic Value of CT Features in Peripheral Solitary Pulmonary Nodule to Determine Benign or Malignant Lesions

Objective:To analyze solitary pulmonary nodules with CT structure around sign in diagnosis of benign and malignant lesions.Methods:Collected 143 cases confirmed of isolated lung knot by pathology and did regular scanning and local thin layer scan.They were divided into two groups,the benign group and malignant group.Then we compared in various signs of statistically different between them,including leaf signs,vascular cut trace syndrome,spines bursting syndrome,Burr syndrome,edge sharp,pleural SAG syndrome,...
