Dense breast tissue has been linked to an increased risk of breast cancer. This is partly a result of difficulties in detecting cancer in dense breasts using conventional mammography. Digital breast tomosynthesis (DBT) is an alternative imaging modality that has shown high sensitivity in dense breast tissue. Because of its 3-D capability, DBT allows more accurate viewing of dense breast tissue by eliminating the overlapping effect associated with 2-D imaging. Although DBT has certain disadvantages, support for DBT is increasing among health care professionals, researchers, and patients.
致密乳腺组织与乳腺癌风险增加有关。部分原因是使用传统乳房X线摄影术在致密乳房中检测癌症存在困难。数字乳腺断层合成（DBT）是一种替代成像方式，在致密乳腺组织中显示出高灵敏度。由于其三维能力，DBT通过消除与二维成像相关的重叠效应，能够更准确地观察致密乳腺组织。尽管DBT有一定的缺点，但医疗保健专业人员、研究人员和患者对DBT的支持正在增加。
