Researchers at St. Jude Children's Research Hospital are looking for more effective ways to deliver radiation therapy to pediatric tumors of the bone and soft tissues. The goal of the study is to improve local control of musculoskeletal tumors with image-guided radiation therapy (IGRT) while minimizing radiation related side effects. IGRT uses computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) images to precisely define tumor location and to carefully plan radiation treatment. This approach allows doctors to deliver highly conformal radiation therapy to the tumor while protecting nearby healthy normal tissues.
