Brief summary
The aim of the study is to assess the accuracy of dynamic contrast enhanced and diffusion-weighted MR Imaging in evaluating response to chemotherapy in osteosarcoma.
Detailed description
Dynamic contrast-enhanced and diffusion-weighted magnetic resonance imaging have the potential to measure early cellular and vascular changes that occur in response to chemotherapy and could therefore be early predictors of therapeutic response. Aim of our study is to assess the accuracy of dynamic contrast enhanced and diffusion-weighted MR imaging in evaluating response to chemotherapy during the preoperative treatment of osteosarcoma. Patients will undergo dynamic contrast-enhanced and diffusion-weighted magnetic resonance imaging before, during and after chemotherapy. Our long-term goal is to use these imaging techniques to develop non-invasive methodologies that would be better predictors of tumor response than the current clinical standard and earlier predictors than histological evaluation of the whole tumor.
