“…In Thailand, the local DRLs for FFDM and DBT were found to be 1.65 mGy and 1.89 mGy, respectively, and were lower than the standard reference levels reported by the IAEA [ 28 ]. In Morocco, the local DRLs for FFDM and DBT were 1.7 mGy and 1.8 mGy, respectively, and were compared with local DRLs from other countries [ 29 ]. In Ghana, the local DRLs for digital mammography were higher than international studies, indicating a need for dose optimization [ 30 ].…”

As the total volume of mammograms in Dubai is increasing consistently, it is crucial to focus on the process of dose optimization by determining dose reference levels for such sensitive radiographic examinations as mammography. This work aimed to determine local diagnostic reference levels (DRLs) for mammography procedures in Dubai at different ranges of breast thickness. A total of 2599 anonymized mammograms were randomly retrieved from a central dose survey database. Mammographic cases for screening women aged from 40 to 69 years were included, while cases of breast implants and breast thickness outside the range of 20–100 mm were excluded. Mean, median, and 75 percentiles were obtained for the mean glandular dose (MGD) distribution of each mammography projection for all compressed breast thickness (CBT) ranges. The local DRLs for mammography in Dubai were found to be between 0.80 mGy and 0.82 mGy for the craniocaudal (CC) projection and between 0.89 mGy and 0.971.8 mGy for the mediolateral oblique (MLO) projection. Local DRLs were proposed according to different breast thicknesses, starting from 20 to 100 mm. All groups of CBT showed a slight difference in MGD values, with higher values in MLO views rather than CC views. The local DRLs in this study were lower than some other Middle Eastern countries and lower than the standard reference levels reported by the International Atomic Energy Agency (IAEA) at 3 mGy/view.

“…In addition, during a mammogram, a woman may have several image acquisition angles and receive repeated doses. These doses received may be associated with a risk of radiation-induced carcinogenesis (Talbi et al, 2022;Wanget al, 2013). The linear no-threshold model of risk evaluation of radiological exposures at low doses remain today appropriate for radiological protection purposes (Laurier et al, 2023a;Laurier et al, 2023b, Bertho andBourguignon, 2023).…”

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.

The objective of this study was to establish local diagnostic reference levels (LDRLs) for breast cancer computed tomography imaging in radiotherapy (CT-RT) at a single hospital in Morocco. Data were collected from 106 adult breast cancer patients aged between 33 and 78 years during five months. Data were obtained using a Hitachi Supria 16-slice CT simulator at a regional oncology center in Morocco. CT-RT images are intended for 3D conformal radiotherapy treatment planning. Dose length product (DLP) and volumetric computed tomography dose index (CTDIvol) were evaluated by determining the 75th percentile as diagnostic reference levels for CT-RT breast cancer. LDRLs for CT-RT breast cancer have been determined in terms of DLP and CTDIvol, and they were 330.4 mGy.cm and 6.8mGy, respectively. The DRLs were compared with other Europeans study. DRLs for this study were lower than those for the United Kingdom (UK), Croatia and Slovenia. The results of this study can be a reference for the establishment of local and national DRLs in Morocco and the optimization of CT-RT breast cancer procedures.
