The simultaneous time-of-flight (TOF) PET/MR clearly identified the untreated tumor parts on the posttherapeutic 90Y internal pair-production imaging. After another boosted 90Y injection, the metastatic hepatic tumors were well covered. The follow-up PET/MR revealed tumor shrinkage. The one-stop-shop TOF PET/MR provided useful follow-up information in patients receiving 90Y radioembolization. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
