The famale's mammary structure characteristics and classification of mammography

目的探讨女性乳腺结构的X线特征及其分型,为中国乳腺癌普查寻找有效手段。方法对随机抽取的1700例(其中门诊1020例,体检680例)绵阳地区的女性进行乳腺X线摄影,以X线影像为基础,进行阅片、分析、统计,并记录X线分型,开展女性乳腺结构的X线特征及其分型研究。结果 1065例为多量腺体型,占62.65%(1065/1700例),282例为致密型,占16.59%(282/1700例),280例为少量腺体型,占16.47%(280/1700例),73例为脂肪型,占4.29%(73/1700例)。结论中国女性乳房较小且较致密,以BI-RADS"乳腺影像报告和数据系统"作为诊断标准分型,方法虽然欠精确,但在临床应用中简便,易掌握,切合实际,可作为乳腺癌的普查手段之一。
