Synthesized 2D (s2D) mammography is rapidly replacing digital mammography in breast imaging with digital breast tomosynthesis (DBT) to reduce radiation dose and maintain screening outcomes. We illustrate variations in the appearance of s2D and digital mammograms to aid in implementation of this technology.
Despite subjective differences in the appearance of s2D and digital mammograms, early outcomes of screening using s2D mammography and DBT are not inferior to those achieved with digital mammography and DBT. Understanding these variations may aid in implementing this technique and improving patient outcomes.
二维合成(s2D)乳腺 X 线摄影术正在迅速取代数字乳腺断层合成术(DBT)中的数字乳腺 X 线摄影术,以降低辐射剂量并保持筛查效果。我们展示了 s2D 和数字乳腺 X 线照片外观上的差异,以帮助实施这项技术。
尽管 s2D 和数字乳腺 X 线照片的外观存在主观差异,但使用 s2D 乳腺 X 线摄影术和 DBT 的筛查早期结果并不逊于使用数字乳腺 X 线摄影术和 DBT 的结果。了解这些差异可能有助于实施这项技术并改善患者的预后。
