Abstract
Purpose: to evaluate the signal characteristics of diffusion weighted MRI sequences of soft tissue tumors in pediatrics and their corresponding ADC measurements and their ability to differentiate between benign and malignant lesions and their response to therapy. Conclusions: DWI and ADC can assist in evaluation of soft tissue masses in conjunction with conventional sequences but do not have high accuracy. They may be used as markers to assess tumor response. Further dedicated study of a bigger sample is recommended to confirm the results of this study, especially concerning follow up of tumors and the use of perfusion insensitive ADC
