Development of Radiation Free Whole Body Magnetic Resonance (MR) Imaging Technique for Staging Children With Cancer
Trial Parameters
Brief Summary
A research study on the diagnosis of spread of disease for children who have been diagnosed with solid tumors using a new whole body imaging technique and a new MR contrast agent (ferumoxytol). Standard tests that are used to determine the extent and possible spread of a child's disease include magnetic resonance (MR) imaging, computed tomography (CT), Positron Emission Tomography (PET) as well as bone scanning, and metaiodobenzylguanidine (MIBG) scanning. The purpose of this study is to determine if newer imaging tests referred to as whole body diffusion-weighted MR and whole body PET/MR can detect the extent and spread of the disease as accurately or even better as the standard tests (CT, MR and/or PET/CT). The advantage of the new imaging test is that it is associated with no or significantly reduced radiation exposure compared to standard CT and PET/CT imaging tests. The results of whole body MR and PET/MR will be compared with that of the conventional, standard imaging studies for tumor detecting.
Eligibility Criteria
Inclusion Criteria: * Diagnosis of a solid extra-cranial tumor like malignant lymphoma or malignant sarcoma and * Scheduled for or completed a 18F-FDG-PET or 18F-FDG-PET/CT tumor staging procedure. * There will be no restrictions on prior treatment. * Very young children who need sedation or anesthesia will be excluded from the study. * In this pediatric \& adult study, the participant or parent/guardian is consented, and the patient when a minor is given an assent form and involved in the discussion as appropriate.
