Diffusion-Weighted Imaging as Predictor of Therapy Response in an Animal Model of Ewing Sarcoma

Abstract

Compared with volumetric measurements, DWI of the viable tumor parts could be used to discriminate between the effects of 2 different dosages at an earlier time point than volumetric measurements in an animal model in vivo. This method could be especially useful for monitoring drug effects in phase I/II clinical trials.
