Recent studies underscore significant progress in radiological and forensic imaging technologies enhancing pediatric and postmortem evaluations. Techniques such as ultrasound-guided hydrostatic reduction improve treatment of pediatric intussusception, while magnetic resonance imaging (MRI) advances illuminate intricate neurodevelopmental and injury patterns in infants and children. Novel methods in postmortem computed tomography angiography (PMCTA) and metabolomic profiling have augmented accuracy in determining cause and time of death. Together, these innovations offer powerful tools to enhance clinical decision-making and forensic investigations, addressing historically challenging diagnostic dilemmas with improved precision.
