摘　　要：目的:探讨低剂量螺旋CT对肺部磨玻璃结节(GGN)性质的诊断价值。方法 :回顾性分析87例肺部低剂量CT检出的GGN,将病灶分为浸润前病变组(34例)、肺腺癌组(53例)。对2组病灶的大小、实性成分、病灶边界、边缘毛刺、分叶、空泡征、血管集束征及胸膜凹陷征等进行对比分析。结果:87例中纯磨玻璃结节(pGGN)36例,混合磨玻璃结节(mGGN)51例。浸润前病变组主要表现为pGGN(28/34,82.35%),肺腺癌组主要表现为mGGN(45/53,84.90%);浸润前病变最大径平均值(11.18±2.68)mm,肺腺癌为(16.43±3.36)mm,2组差异均有统计学意义(均P<0.001)。2组GGN中实性成分、毛刺、分叶比较差异均有统计学意义(均P<0.05);而2组病灶边界是否清晰、空泡征、血管集束征、胸膜凹陷征比较差异均无统计学意义(均P> 0.05)。结论:低剂量螺旋CT对肺部GGN性质的判断具有重要临床价值。Objective:To investigate the value of low-dose spiral CT in the diagnosis of ground glass nodules(GGN)in lung.Methods:A retrospective analysis of 87 low-dose lung CT showed GGN.The lesions were divided into two groups:preinvasive lesion group(34 cases),lung adenocarcinoma group(53 cases).The lesion size,solid components,lesion borders,burrs,lobulation,air-containing space,vessel convergence sign and pleural indentation of the two groups were compared and analyzed.Results:Among the 87 cases of pulmonary GGN,pGGN was found in 36 cases,and mGGN in 51 cases.pGGN was mainly in preinvasive lesion group(28/34,82.35%),however,mGGN was mainly in lung adenocarcinoma group(45/53,84.90%).Mean size of two groups were(11.18±2.68)mm and(16.43±3.36)mm for preinvasive lesion group and lung adenocarcinoma group,there was a statistically significant difference between the two groups(P<0.001).There were statistically significant differences in solid component,burrs,lobulation,pleural indentation between the preinvasive lesion group and lung adenocarcinoma group(P<0.05 for all).However,there was no significant difference in lesion borders,air-containing space,vessel convergence sign between two groups(P>0.05 for all).Conclusion:Low-dose spiral CT scan has important value for the diagnosis of pulmonary characteristic of GGN.
