Digital breast tomosynthesis (DBT) is emerging as the standard of care for breast imaging based on improvements in both screening and diagnostic imaging outcomes. The additional information obtained from the tomosynthesis acquisition decreases the confounding effect of overlapping tissue, allowing for improved lesion detection, characterization, and localization. In addition, the quasi three-dimensional information obtained from the reconstructed DBT data set allows a more efficient imaging work-up than imaging with two-dimensional full-field digital mammography alone. Herein, the authors review the benefits of DBT imaging in screening and diagnostic breast imaging.
数字乳腺断层合成术（DBT）在改善筛查和诊断成像结果的基础上，成为乳腺成像的标准护理方法。从断层合成术获取的额外信息减少了重叠组织的混杂影响，从而提高了病变检测、特征描述和定位的能力。此外，从重建的 DBT 数据集获得的准三维信息使得与单独使用二维全数字化乳腺摄影相比，能够更有效地进行成像检查。在此，作者综述了 DBT 成像在筛查和诊断性乳腺成像中的益处。
