RADIATION EXPOSURE IN ROUTINE MAMMOGRAPHY SCREENING: A LARGE OBSERVATIONAL CROSS-SECTIONAL STUDY IN MOROCCO

Abstract

This observational cross-sectional study aimed to assess radiation exposure during mammography for breast cancer screening in Morocco and highlight the importance of dose optimization.
 Patient data from 1100 mammographic examinations conducted in five units in the Rabat-Salé-Zemmour-Zaër region were collected. The mean glandular dose (MGD) and technical parameters, such as exposure factors and breast thickness, were analyzed. The data were compared with international studies to provide context.
 The overall mean MGD was 1.34 ± 0.36 mGy for craniocaudal (CC) and 1.48 ± 0.38 mGy for mediolateral oblique (MLO) incidences. The MGD varied among different units and anode/filter combinations. The Rh/Rh anode/filter combination was most commonly used, resulting in the lowest radiation dose. The study findings also highlighted the relationship between MGD and breast thickness, with higher doses observed for thicker breasts.
 This study provides valuable insights into radiation exposure during mammography breast cancer screening in Morocco. The results underscore the importance of dose optimization strategies to ensure patient safety without compromising diagnostic image quality. Implementing optimized technical parameters, conducting regular quality assurance programs, and promoting education and awareness are essential in achieving dose reduction and minimizing radiation risks. Collaboration among healthcare professionals, regulatory bodies, and international organizations is crucial for sharing best practices and advancing radiation dose optimization in mammography.
