Clinical Indication-Based Pediatric Diagnostic Reference Level Values for Abdominal Computed Tomography: A Descriptive Cross-Sectional Study. [PDF]

open access: yesHealth Sci Rep
ABSTRACT Background and Aims Computed tomography (CT) poses a concern in pediatric patients because of their higher sensitivity to radiation. At the time of the study, nephroblastoma was the most prevalent clinical indication for abdominal CT examinations in pediatric patients.
