Receiver operator characteristics of NB and GNB/GN for mean, median and 5th percentile of the ADC values. Figure 2 shows receiver operator characteristics for mean, median, and 5th percentile of the ADC values (× 10− 6 mm2/s) of the whole tumor volume for differentiation between NB and GNB/GN after chemotherapy. The 5th percentile is suited best for distinguishing histopathological subtypes with an area under the curve of 0.848 after chemotherapy. Abbreviations: ADC: apparent diffusion coefficient; NB: neuroblastoma; GNB: ganglioneuroblastoma; GN: ganglioneuroma
