MYCN and neoplasm: In recent years, several radiomics studies of malignant PNTs have reported features associated with the prediction of tumor histology,[23] MYCN amplification status,[24–26] bone marrow involvement,[27] response to neoadjuvant chemotherapy,[28] recurrence,[29] prognosis,[30] and differentiation between high-risk and non-high-risk groups.[31] Nearly half of the radiomics studies were based on 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT).
