“…As already mentioned elsewhere [ 17 ], 96% of the population is urban, with a median age of 32.3 y, and consists of expats that come to the country for work. Due to the huge influx of male workforce, women account for just 25% of the population.…”

“…In an attempt to evaluate patient radiation exposure based on CI and investigate the possibility of establishing institutional clinical DRLs in the State of Qatar, the first meeting was held in February 2019 with representatives of the respective radiology departments (the main health care provided in Qatar), Hamad Medical Corporation (HMC) Medical Physics Section, and the Medical Physics Society. During the initial meeting, the CIs to focus on were decided and chosen because of the high frequency in the state of Qatar and because of the possible increased radiation exposure of patients [ 17 ].…”

This study focuses on patient radiation exposure in interventional neuroradiology (INR) procedures, a field that has advanced significantly since its inception in the 1980s. INR employs minimally invasive techniques to treat complex cerebrovascular diseases in the head, neck, and spine. The study establishes diagnostic reference levels (DRLs) for three clinical indications (CIs): stroke (S), brain aneurysms (ANs), and brain arteriovenous malformation (AVM). Data from 209 adult patients were analyzed, and DRLs were determined in terms of various dosimetric and technical quantities. For stroke, the established DRLs median values were found to be 78 Gy cm2, 378 mGy, 118 mGy, 12 min, 442 images, and 15 runs. Similarly, DRLs for brain AN are 85 Gy cm2, 611 mGy, 95.5 mGy, 19.5, 717 images, and 26 runs. For brain AVM, the DRL’s are 180 Gy cm2, 1144 mGy, 537 mGy, 36 min, 1375 images, and 31 runs. Notably, this study is unique in reporting DRLs for specific CIs within INR procedures, providing valuable insights for optimizing patient safety and radiation exposure management.

“…MGD or average glandular dose (AGD) is a measure utilized to quantify the amount of radiation absorbed by the breast during mammography. This value is estimated using standard breast parameters, such as the entrance surface air kerma (ESAK) and HVL [ 18 ]. The MGD was determined individually using the approach developed by Dance [ 15 , 19 ].…”

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.
