Pediatric Oncologic Imaging: A Key Application of Combined PET/MRI.UNLABELLED
 Pediatric imaging has been identified as a key application of combined whole-body PET/MRI.  First studies have revealed the clinical feasibility and possible advantages of PET/MRI over PET/CT and MRI.  Besides a significant reduction in radiation exposure of about 50 - 75 %, combined whole-body PET/MRI offers the diagnostic advantage of the multiparametric characterization of pathophysiologic processes and helps reduce the number of necessary imaging studies.  However, very few studies focusing on pediatric PET/MRI have been published to date.  This review article shall summarize the existing literature concerning pediatric PET/MRI and give insight into the practical experience derived from over 160 pediatric PET/MRI examinations that were performed in Tübingen.


 •Combined PET/MR is a promising imaging modality in pediatric oncology.  •Using combined PET/MRI, diagnostic radiation exposure of pediatric patients and the number of necessary imaging studies can be reduced.  •Further clinical studies are necessary in order to define specific indications for combined PET/MRI in pediatric radiology.
