摘要 目的分析不同年龄段妇女排卵前、后乳腺实质表观弥散系数(ADC)的差异。方法选择2009年11月至2010年4月志愿参与本研究的月经正常妇女65名,其中20~<35岁30名,35~49岁35名;排卵前、后1周内各行1次磁共振平扫及扩散加权成像检查未发现乳腺疾患。根据wolf分型,所有乳腺均为致密型或分叶串珠型,扩散敏感因子———b值取0、1 000s/mm2,测量双乳130个乳房乳头层面乳腺实质平均ADC值。结果同年龄段志愿者排卵前乳腺实质ADC值均低于排卵后,差异有统计学意义(P<0.05);排卵前或排卵后,两个年龄段志愿者ADC值比较差异无统计学意义(P>0.05)。结论致密型或分叶串珠型乳腺实质排卵前ADC值明显较低,年龄因素对此两型乳腺实质ADC值影响较小。
