Summary: Patients with complex polytrauma in military and civilian settings are exposed to substantial diagnostic medical radiation, increasing the risk of subsequent malignancy. Currently, there is no coordinated effort to track radiation exposure or long-term surveillance for such patients. This study aims to quantify radiation exposure for combat-wounded servicemembers and determine its correlation with the Injury Severity Score (ISS).

Summary: This study aims to establish pediatric fluoroscopic DRLs in a South Australian tertiary hospital and compare them with previously published data, as well as explore the relationship between DAP, age, and fluoroscopy time. The local DRLs were significantly lower than the previous data, reflecting technological and procedural advancements.

Summary: Today's orthopedic surgery relies heavily on intraoperative X-ray imaging. Recent advances have not only improved the quality of imaging, but also transformed the way information is processed and presented. These developments will revolutionize the integration of imaging technology in surgical procedures.

Summary: This study aimed to compare the differences in subject radiation exposure, procedure time, yield, and adverse events between helical CT and intermittent CT fluoroscopy guidance in musculoskeletal needle biopsies. The results showed that intermittent CT fluoroscopy can reduce subject radiation dose without negatively affecting outcomes and adverse event rate.

Summary: This study aimed to evaluate the diagnostic performance and inter-reader agreement of a novel "Darth Vader sign" for detecting spondylolysis in non-musculoskeletal abdominal CT imaging. The results showed that the Darth Vader sign demonstrated good inter-reader agreement and excellent diagnostic capabilities with high sensitivity and specificity for detecting spondylolysis.

Summary: The study demonstrates that serum miRNAs can be used as functional biodosimeters to predict the biological impact of radiation doses in humans undergoing total body irradiation. A logistic regression model was built using miR-150-5p, miR-30b-5p, and miR-320c, which showed high accuracy in identifying samples drawn after irradiation.

Summary: This study compares the occupational radiation dose levels for 145 workers in four different hospitals in the Aseer region, Saudi Arabia. The results show that the average yearly cumulative dose for workers in various diagnostic radiology procedures is 1.42 mSv, with the highest dose at 3.9 mSv and the lowest at 0.72 mSv, all within the IAEA approved yearly dose limit for occupational exposure.

Summary: Evidence suggests an excess risk of childhood cancer after medical diagnostic radiation exposure in utero or in childhood, with recent studies indicating reduced risk. Postnatal exposure to diagnostic radiation is associated with significant excess risks of leukemia, brain, and solid cancers, with variations in risk by cancer type and type of exposure. However, there is significant heterogeneity among studies on postnatal exposure, which affects the strength of evidence for a causal relationship between childhood radiation imaging and subsequent cancer risk.

Summary: This study measured individual organ doses during CT scanning and found that the doses for whole-body routine CT protocols were generally below 20 mGy, indicating relatively low radiation exposure. Surface/shallow organs had higher doses than deep organs, and internal organ doses were significantly higher during whole-body scans compared to abdominal scans. This information provides valuable insights for considering CT examinations in daily clinical situations.

Summary: This article discusses the guidelines for establishing and using local Diagnostic Reference Levels (DRLs), emphasizing their importance. Local DRLs can be determined by collecting a reasonable amount of data and calculating the 3rd quartile values to define the 'typical values'. Local DRLs should be similar or lower than the national DRLs and can be used as quality benchmarks and alert values.

Summary: This paper proposes a simple scheme to alleviate the nonuniform temporal gain (NTG) problem in fluoroscopic imaging for accurately and efficiently measuring the detector lag correction factor (LCF). By using conditional covariance to calculate correlation coefficients, the proposed approach can obtain accurate LCF values even under the NTG environment without any preprocessing scheme.

Summary: CTC is an effective imaging technique for colon and rectum malignancy, but requires dose evaluation to balance benefits and risks. A study on 55 CTC procedures found variations in effective dose based on CT machine, protocol, and technologist's role, with automatic tube current modulation showing significant impact on dose.
