Impact of breast implant presence and type on mean glandular dose calculations

Purpose: Breast cancer remains the most frequently diagnosed cancer among women, making mammography a vital tool for its early detection. However, the increasing prevalence of breast augmentation raises concerns about the accuracy of radiation dose estimation during mammography. Material and methods: This study investigates the impact of breast implants on mean glandular dose (MGD) calculations in mammography using Monte Carlo simulations. The research uses the GATE simulation framework to model different implant types (saline, silicone, and adipose tissue) to evaluate their influence on the conversion factors used to determine MGD. Results: The results indicate that the standard conversion factors, derived for non-augmented breasts, may not accurately reflect MGD in augmented breasts. Conclusions: The study highlights the need for tailored conversion factors to ensure precise radiation dose estimation in women with implants, ultimately improving individualized mammography protocols.
