Although a recent study has shown the potential of CT-based signature in the prediction of MYCN amplification of NB and ganglioneuroblastoma (GNB) (8), there were some problems with the patients’ selection, in which nonabdominal NB and GNB were also enrolled, because previous literatures have demonstrated that MYCN amplification rarely occurs in nonabdominal NB and GNB (13, 14). Here, MYCN is linked to ganglioneuroblastoma.
