Background: Bone scans using technetium-99m methylene diphosphonate (99mTc-MDP) are widely used in nuclear medicine for diagnosing various bone disorders. However, the radiation exposure associated with these procedures necessitates careful consideration and optimization.
Aim: This study aimed to evaluate radiation doses in terms of Effective Dose (ED) and establish Diagnostic Reference Levels (DRLs) for 99mTc-MDP bone scans in Saudi Arabia.

Prenatal lead (Pb) and manganese (Mn) exposure can impair neurodevelopment, targeting the central nervous system. This study investigated the effects of prenatal exposure to Pb and Mn on neurodevelopment in children at 18 months of age, using data from 607 Italian mother-child pairs enrolled in the Northern Adriatic Cohort II (NAC-II). All children born at term (≥37 weeks) were assessed with the Bayley Scales of Infant and Toddler Development, third edition.

Few epidemiological studies have investigated associations between anthropogenic heat emissions (AE) and serum lipids. We recruited 15,477 adults from 33 communities in northeastern China in 2009. We estimated AE flux by using data on energy consumption and socio-economic statistics covering building, transportation, industry, and human metabolism.

Objective: To characterize the cerebrospinal fluid (CSF) of infants with stroke and compare those findings to the CSF of infants with bacterial meningitis and neither condition in the first 14 postnatal days.
Study Design: Cohort study of 30,092 infants who received a lumbar puncture in the first 14 postnatal days discharged from >300 neonatal intensive care units from 1997-2020. CSF parameters were compared between infants with stroke and bacterial meningitis using non-parametric hypothesis testing and quantile regression.

Objective: To establish local diagnostic reference levels (DRLs) for pediatric neck CT based on age, weight, and water-equivalent diameter (WED) across multiple university hospitals in South Korea.
Materials And Methods: This retrospective study analyzed pediatric neck CT examinations from nine university hospitals, involving patients aged 0-18 years. Data were categorized by age, weight, and WED, and radiation dose metrics, including volume CT dose index (CTDI) and dose length product, were recorded.
