“…This is higher than the previously registered national value from Saudi Arabia of 1.1 mGy. 22 However, both values were lower than the 3.0 mGy benchmark set by the International Atomic Energy Agency. 23 Hence, data management facilitated the maintenance of patient dosimetry, acquisition of medical imaging data, and exploration of ADs and DRLs in mammography.…”

“…25 Using a similar mammography system as in our study, Kawaguchi 26 obtained an average AGD of 1.6 Gy; however, this value was slightly lower than the AGD value obtained in our study (Table 3). 22 In the aforementioned Norwegian study, 25 variations in AGD values can be partially explained by the recent trend toward using a higher ESD exposure with an expected increase in AGD. 26 Nonetheless, Warren et al, 27 Hauge et al, 28 and Baeck et al 29 have reported AGD values of 0.01, 8.2, and 3.6 mGy, respectively.…”

To evaluate the impact of using computational data management resources and analytical software on radiation doses in mammography and radiography during the COVID-19 pandemic, develop departmental diagnostic reference levels (DRLs), and describe achievable doses (ADs) for mammography and radiography based on measured dose parameters. Patients and Methods: This ambispective cohort study enrolled 795 and 12,115 patients who underwent mammography and radiography, respectively, at the King Fahd Hospital of the University, Al-Khobar City, Saudi Arabia between May 25 and November 4, 2021. Demographic data were acquired from patients' electronic medical charts. Data on mammographic and radiographic dose determinants were acquired from the data management software. Based on the time when the data management software was operational in the institute, the study was divided into the pre-implementation and post-implementation phases. Continuous and categorical variables were compared between the two phases using an unpaired t-test and the chi-square test. Results: The median accumulated average glandular dose (AGD; a mammographic dose determinant) in the post-implementation phase was three-fold higher than that in the pre-implementation phase. The average mammographic exposure time in the postimplementation phase was 16.3 ms shorter than that in the pre-implementation phase. Furthermore, the median values of the dose area product ([DAP], a radiographic dose determinant) were 9.72 and 19.4 cGycm 2 in the pre-implementation and post-implementation phases, respectively. Conclusion: Although the data management software used in this study helped reduce the radiation exposure time by 16.3 ms in mammography, its impact on the mean accumulated AGD was unfavorable. Similarly, radiographic exposure indices, including DAP, tube voltage, tube current, and exposure time, were not significantly different after the data management software was implemented. Close monitoring of patient radiation doses in mammography and radiography, and dose reduction will become possible if imaging facilities use DRLs and ADs via automated systems.

“…1, 2 The mortality rate in patients with breast cancer can reach up to 30.7%, accounting for 11.6% of total cancer deaths. [3][4][5] Furthermore, it is stated that a woman has a 12% risk of developing breast cancer throughout her lifetime. 5, 6 Due to its high prevalence and mortality rates, early diagnosis of breast cancer is crucial.…”

“…In order to generate high-quality images in denser breasts, it may be necessary to use more X-rays, which can result in higher radiation exposure. 5 Additionally, it is stated that women with denser and larger breasts may have a higher radiogenic risk. 5 To assess a patient's radiation-induced exposure, the average glandular dose (AGD) is evaluated and expressed in mGy (milligray).…”

Aims: To determine the average radiation dose values in patients who underwent routine screening mammography in our hospital, establish the relationship between breast density and volume, and investigate other factors affecting radiation dose. Methods: Screening bilateral mammography was retrospectively evaluated within the specified period of 2 months. Patient age, breast density ratio, mammographic size of the breast, calculated breast volume, tube voltage, current, exposure time (ms), compression force (kg), compression thickness (mm), and radiation dose (mGy) given in each projection were recorded separately for each patient. According to the BI-RADS, breast densities classified as types A-B were considered non-dense, while types C-D were considered dense breasts. The 75th percentile dose value (mGy) was chosen as the cutoff for high dose group. Logistic regression analyses were used to examine the factors affecting radiation dose. Results: 1720 mammograms from 430 patients were studied. 276 (64.2%) breasts were non-dense, while 154 (35.8%) breasts were dense. The mean total breast volume was 595±334 ml, compression thickness was 36.5±12.0 mm, and radiation dose was 2.04±0.75 mGy. There was a negative correlation between radiation dose and age (r=-0.330, p
