## Abstract

Positron emission tomography (PET) and magnetic resonance imaging (MRI) offer complementary information about the human brain in health and disease. The simultaneous 7 T MR-BrainPET insert enables molecular imaging quantification beyond the current limits. Here we present the current status of the field highlighting PET/MR synergies for the image-derived input function (IDIF). We also discuss promising applications that will benefit from these advancements, as well the challenges to be addressed in the near future.
