Abstract
目的 评价CT引导下经皮肺穿刺活检(PTNB)对肺局灶性磨玻璃影(GGO)的诊断价值.方法 回顾性分析CT引导下PTNB 53例肺局灶性GGO患者的临床资料,根据穿刺活检病理和胸腔镜手术病理对照,比较CT引导下对PTNB>8mm/≤8mm局灶性GGO的活检病理准确率和部分实性GGO/纯GGO的病理准确率.结果 CT引导下PTNB对>8mm局灶性GGO活检病理准确率为91.11 (41/45)/≤8mm局灶性GGO活检病理准确率为37.50(3/8);两者差异有统计学意义(x2=10.306,P<0.05).部分实性GGO的活检病理准确率为87.18(34/39),纯GGO的活检病理准确率为71.43(10/14);两者差异无统计学意义(x2=3.102,P>0.05).结论 CT引导下PTNB对于>8mm肺局灶性GGO具有较高的诊断价值.
