OBJECTIVE. Digital breast tomosynthesis (DBT) is a recent imaging technology that was developed to address the limitations of conventional 2D mammography. The limitations of standard mammography are well known and include reduced sensitivity in dense breasts. Clinical research studies of DBT and the implementation of DBT have revealed that DBT has potential benefits for evaluating patients with dense breasts. This article will discuss the benefits and limitations of DBT as a screening alternative for women with dense breasts. CONCLUSION. Studies to date have revealed that the use of DBT reduces recall rates and increases cancer detection rates. This has been demonstrated with the use of DBT for both screening and diagnostic purposes, as well as with imaging dense breasts. DBT has the ability to reduce breast tissue overlap, thus potentially revealing lesions that would otherwise have been missed. The limitations of DBT include longer interpretation times, higher costs, and increased radiation dose. These limitations present challenges that radiologists must consider before DBT implementation.
目的。数字乳腺断层合成（DBT）是一种最新的成像技术，其开发旨在解决传统二维乳腺摄影的局限性。标准乳腺摄影的局限性众所周知，包括在致密型乳腺中敏感性降低。DBT的临床研究及DBT的应用表明，DBT在评估致密型乳腺患者方面具有潜在益处。本文将探讨DBT作为致密型乳腺女性筛查替代方法的益处和局限性。结论。迄今为止的研究表明，使用DBT可降低召回率并提高癌症检出率。这已在DBT用于筛查和诊断目的以及对致密型乳腺成像时得到证实。DBT能够减少乳腺组织重叠，从而有可能发现原本会被漏诊的病变。DBT的局限性包括解读时间更长、成本更高以及辐射剂量增加。这些局限性带来了放射科医生在实施DBT之前必须考虑的挑战。
