This co-provided workshop, presented by the Society of Nuclear Medicine and Molecular Imaging's (SNMMI) PET Center of Excellence and the International Society for Magnetic Resonance in Medicine (ISMRM), will focus on both the technical aspects of PET/MRI as well as the clinical utility of PET/MRI. The workshop will feature a mixture of invited scientific presentations, proffered papers, a poster session, small group discussion, and a keynote lecture. A young investigator award will be presented to students and early stage post-doctoral or physicians that will be selected from the oral paper presentations.
