Neuroblastoma (NB) is the most common extracranial solid tumor in childhood. High-risk patients have still a poor prognosis despite the therapeutic progress. The aim of this study is to assess by Magnetic Resonance Imaging (MRI) the physiological changes (perfusion and hypoxia) induced by an experimental anticancer therapy tested in a well-characterized preclinical transgenic neuroblastoma murine model. Our results show a decrease of the Ktrans parameter and relaxivity R2* value in treated mice compared to control, suggesting an impact of such therapy on vessels normalization.
