This study aimed to assess radiologists' knowledge about breast density legislation as well as perceived practice changes resulting from the enactment of breast density legislation.
This is an institutional review board-exempt anonymous email survey of 523 members of the New England Roentgen Ray Society. In addition to radiologist demographics, survey questions addressed radiologist knowledge of breast density legislation, knowledge of breast density as a risk factor for breast cancer, recommendations for supplemental screening, and perceived practice changes resulting from density notification legislation.
Of the 523 members, 96 responded, yielding an 18% response rate. Seventy-three percent of respondents practiced in a state with breast density legislation. Sixty-nine percent felt that breast density notification increased patient anxiety about breast cancer, but also increased patient (74%) and provider (66%) understanding of the effect of breast density on mammographic sensitivity. Radiologist knowledge of the relative risk of breast cancer when comparing breasts of different density was variable.
Considerable confusion and controversy regarding breast density persists, even among practicing radiologists.
本研究旨在评估放射科医生对乳腺密度立法的了解程度，以及乳腺密度立法实施后所察觉到的实践变化。
这是一项针对新英格兰伦琴射线协会523名成员的、经机构审查委员会豁免的匿名电子邮件调查。除了放射科医生的人口统计学信息外，调查问题还涉及放射科医生对乳腺密度立法的了解、对乳腺密度作为乳腺癌风险因素的认识、补充筛查的建议，以及密度通知立法导致的实践变化。
523名成员中，96人回复，回复率为18%。73%的受访者在有乳腺密度立法的州执业。69%的人认为乳腺密度通知增加了患者对乳腺癌的焦虑，但也增加了患者（74%）和医生（66%）对乳腺密度对乳腺钼靶敏感性影响的理解。放射科医生对不同密度乳房乳腺癌相对风险的了解各不相同。
即使在执业放射科医生中，关于乳腺密度的困惑和争议仍然很大。
