Imaging defined risk factors in neuroblastoma – guidelines for optimising imaging interpretations
- Valchev, B. Balev
Neuroblastoma is the most frequent extracranial tumor in children, arising from the primitive sympathetic cells and the adrenal medulla. Two separate mutually complementing staging systems exist – INSS and INRGSS – one is based on post-operative findings, the other – on pre-treatment imaging. INRGSS consists of a list of 20 separate imaging defined risk factors (IDRF), the presence of which could alter the treatment plan. Radiologists need to be aware of certain intricacies in interpreting the individual IDRFs in order to optimise clinical decision-making.
