The purpose is to compare full-field digital mammography (FFDM), digital breast tomosynthesis (DBT) and contrast-enhanced spectral mammography (CESM) technologies on three mammography systems in terms of image quality and patient dose. Two Senographe Essential with DBT and CESM (denoted S1 and S2) and one Selenia Dimensions (S3) with FFDM and DBT were considered. Dosimetry methods recommended in the European protocol were used. Image quality was tested with CDMAM in FFDM and DBT and with ideal observer method in FFDM. Mean values of mean glandular dose (MGD) from whole patient samples on S1, S2 and S3 were as follows: FFDM 1.65, 1.84 and 2.23 mGy; DBT 2.03, 1.96 and 2.87 mGy; CESM 2.65 and 3.16 mGy, respectively. S3 exhibited better low-contrast detectability for the smallest sized discs of CDMAM and ideal observer in FFDM, and for the largest sized discs in DBT, at similar dose levels.
目的是比较三种乳腺摄影系统中全数字乳腺摄影（FFDM）、数字乳腺断层摄影（DBT）和对比增强光谱乳腺摄影（CESM）技术在图像质量和患者剂量方面的差异。考虑了两台配备 DBT 和 CESM 的 Senographe Essential（分别表示为 S1 和 S2）和一台配备 FFDM 和 DBT 的 Selenia Dimensions（S3）。使用欧洲协议中推荐的剂量学方法进行测量。使用 FFDM 和 DBT 中的 CDMAM 测试图像质量，并用 FFDM 中的理想观察者方法进行测试。从 S1、S2 和 S3 的全患者样本中得出的平均腺体剂量（MGD）的平均值分别为：FFDM 为 1.65、1.84 和 2.23 mGy；DBT 为 2.03、1.96 和 2.87 mGy；CESM 为 2.65 和 3.16 mGy。在相似的剂量水平下，S3 在 FFDM 中对 CDMAM 和理想观察者的最小尺寸圆盘以及 DBT 中的最大尺寸圆盘具有更好的低对比度检测能力。
