Exposure of children with neuroblastoma to ionizing radiation during computed tomography and nuclear medicine imaging – a single centre experience

Purpose: To calculate cumulative doses of ionizing radiation absorbed by children with neuroblastoma during diagnostic CT and NM scans. Method: Retrospective analysis of 267 CT and NM scans performed in 21 children treated in 2009–2015. Results: The cumulative effective dose absorbed per child ranged from 58 to 536 mSv and was highest in infants under 3 years. Conclusion: Children with suspected neuroblastoma may be exposed to significant doses of radiation during the whole period of diagnosis and monitoring the progress of treatment.
