a and b Example of NB (a) and GNB (b) after neoadjuvant therapy in T2 weighted and diffusion weighted imaging. These figures depict an example of a NB (a) and GNB (b) after neoadjuvant therapy with T2 weighted and diffusion weighted imaging (b = 1000 s/mm2) as well as the corresponding ADC map. The NB appears more heterogenous than the GNB, especially in the ADC map. The 5th percentile of the ADC values resulted in 977.5 × 10− 6 mm2/s for the NB and 1199.0 × 10− 6 mm2/s for the GNB. Abbreviations: NB: neuroblastoma; GNB: ganglioneuroblastoma; ADC: apparent diffusion coefficient
