Abstract:	Objectives: This retrospective study aimed to compare the average glandular dose (AGD) per acquisition in breast biopsies guided by contrast-enhanced mammography (CEM), conventional stereotactic breast biopsy (SBB), and digital breast tomosynthesis (DBT). The study also investigated the influence of compressed breast thickness (CBT) and density on AGD. Furthermore, the study aimed to estimate the AGD per procedure for each guidance modality. Methods: The study included 163 female patients (mean age 57 ± 10 years) who underwent mammography-guided biopsies using SBB (9%), DBT (65%), or CEM (26%) guidance. AGD and CBT data were extracted from DICOM headers, and breast density was visually assessed. Statistical analyses included two-sample t-tests and descriptive statistics. Results: Mean AGD per acquisition varied slightly among CEM (1. 48 ± 0. 22 mGy), SBB (1. 49 ± 0. 40 mGy), and DBT (1. 55 ± 0. 47 mGy), with CEM presenting higher AGD at lower CBTs and less dose escalation at higher CBTs. For CBT.
