Whole body MRI plays an increasingly important role in the primary diagnosis and follow-up of pediatric patients with oncologic disorders. High anatomical resolution, excellent soft tissue contrast and functional imaging techniques enable accurate local staging of primary tumors as well as sensitive detection of distant metastases. However, image quality and patient compliance depend on the chosen protocol, which should be composed carefully according to the clinical question. Recently, combined simultaneous PET/MRI was introduced adding metabolic information for tumor characterization. Patient preparation and imaging protocols are of higher complexity due to tracer injection and parallel acquisition of PET and MR data. Furthermore, radiation doses should be kept to a minimum. This educational poster shall give an overview over clinical indications and technical aspects of pediatric oncologic whole body MRI and PET/MRI with respect to patient preparation, imaging protocols and specifics in image analysis.
