About 25% of women older than 40 years have dense breast tissue, which makes it particularly difficult to distinguish between healthy and tumor tissue on a mammogram."We all know that mammography is not perfect," commented Eric Winder, MD, professor of medicine at the Dana Farber Cancer Institute, in Boston, Massachusetts. This new technique could be a useful adjunct, particularly in women with dense breasts. There is already increasing use of magnetic resonance imaging in such women, he noted, and this technique might offer an alternative."Strategies for breast cancer screening are becoming more individualized, and we are moving away from a 1-size-fits-all scenario," he commented at an ASCO press briefing that he moderated.

40岁以上的妇女有大约25%有致密乳房组织，使得特别难以藉由乳房摄影区别健康组织和肿瘤组织；达那-法柏癌症研究治疗中心医学教授、Eric Winder医师表示，我们都知道乳房摄影不是最好的，这个新技术可以是有用的辅助方式，特别是属於致密乳房组织的妇女；他指出，这类妇女使用磁振造影的人数已经增加，此技术或许可以提供另一种选择；他在主持ASCO的记者会时表示，乳癌筛检策略变得个人化，我们已经不再用一体适用的方案。
