Abstract:

目的探讨乳腺影像报告和数据系统(BI-RADS)分级在超声引导下乳腺穿刺活检中的应用价值。方法从2010年1月-2014年3月在我院行彩色多普勒超声扫查的乳腺疾病患者中抽选BI-RADS分级为3、4、5级的患者127例,并结合穿刺活检病理结果进行分析,评估BI-RADS分级对乳腺恶性病灶诊断的灵敏度、特异性、准确度、阳性及阴性预测值(PPV、NPV),比较各分级的PPV差异。结果BI-RADS3级、4级、5级三组患者在病变边缘、血流阻力指数(RI)、边界、钙化、回声、周围组织以及血管分布等超声表现上比较差异有统计学意义(P<0.05)。127例患者穿刺活检病理结果显示良性病变68例(53.5%)、恶性病变59例(46.4%)。BI-RADS分级诊断乳腺恶性病灶的灵敏度、特异性、准确度、PPV、NPV分别为94.9%、73.5%、83.5%、75.7%、94.3%;并且3、4a、4b、4c、5级等各分级的PPV比较差异有统计学意义(P<0.05)。结论BI-RADS评估标准对乳腺良恶性病变的诊断及鉴别诊断价值较高。
