“…The DRL values for CT examinations were reported in six studies: two reported the DRLs for children (Rawashdeh et al 2019; Rawashdeh et al 2023); one reported the DRL for cardiac CT examinations (Rawashdeh et al 2019); one reported the DRL for renal CT (Rawashdeh and Saade 2023) examinations; and the last two were reported DRLs for CT of chest, abdomen, pelvis, and brain CT (Radaideh et al 2023; Al Ewaidat et al 2018). All studies determined the DRL values of the CT scans using patient level data.…”

“…The two most often used measurements for determining DRL were the CTDI vol and the DLP. One study included the effective dose (Rawashdeh et al 2023), and the other study included the SSDE as additional measurements. The DRLs were typically reported as means, medians, and third quartile values.…”

“…The rest of the studies reported the same quantities of CTDI vol and DLP (median and 75 th ) but for different body parts (Rawashdeh et al 2019; Rawashdeh et al 2023; Radaideh et al 2023). The median–75 th CTDI vol for adult chest was 12.86-16 m Gy, and the DLP was 453-583 mGy cm −1 (Radaideh et al 2023).…”

“…In recent years, it has become more common to base DRL values on SSDEs. However, DRL values based on SSDEs have only been published in one study in Jordan for pediatric CT (Rawashdeh et al 2023). Rawashdeh et al (2023) reported the values of CTDI vol and 75 th for different age groups <1, 1-4, 5-10, and 11-18 for brain, chest, and chest/abdomen/pelvis examinations.…”

A comprehensive search was performed to examine the literature on diagnostic reference levels (DRL) for computed tomography (CT) and radiography examinations that are performed routinely in Jordan. EBSCO, Scopus, and Web of Science were used for the search. The acronym “DRL” and the additional phrase “dose reference levels” were used to search for articles in literature. Seven papers that reported DRL values for radiography and CT scans in Jordan were identified. One study reported DRLs for conventional radiography, two studies reported CT DRLs in pediatrics, and the remaining four studies provided DRL values for adult CT scans. The most popular techniques for determining the DRLs were the entrance surface dose, volume CT dose index (CTDIvol), and dose-length product (DLP) values. Variations in Jordanian DRL values were noted across both modalities. Lower radiation doses and less variation in DRL values may be achieved by educating and training radiographers to better understand dose reduction strategies. To limit dose variance and enable dosage comparison, CT DRLs must be standardized in accordance with the guidelines of the International Commission on Radiological Protection (ICRP).
