A study published in the Journal of Nuclear Medicine indicated that successive PET/CT and diffusion-weighed MRI may aid in monitoring and predicting response after neoadjuvant chemotherapy in patients with osteosarcoma. Researchers performed PET/CT and MRI scans on patients before and after chemotherapy and measured change in standardized uptake value and change in apparent diffusion coefficient of the bone cancer, finding the parameters were useful for predicting histologic response. The methods have also been useful in identifying suspicious lesions in patients.
