Stanford University
The primary goal of this project is to study the feasibility of a brain-dedicated PET insert for an MR scanner for simultaneous acquisition of PET/MR images of human brains. The study will also allow us to compare the imaging performance of the investigator's brain-dedicated PET insert against a commercial whole-body permanently integrated PET/MRI system using a common radiopharmaceutical.
This study will enroll up to 40 participants. 1. 20 participants at Stanford injected with an FDA-approved PET tracer (e.g. amyloid, FDG, etc.), and 2. 20 participants from Stanford who have been pre-injected with a radiopharmaceutical for a study on another PET imaging system
Inclusion Criteria: 1. Whole body radiation dose within the last year of less than 5000 mrem 2. Subjects intended for injected tracer studies (not associated with another study) must be willing/able to undergo injection of 6-12 mCi of either FDG or Neuraceq radiotracer. Both tracers are FDA approved 3. Subjects will be at least 21 years of age 4. Subject provides written informed consent 5. Subject is deemed healthy by the PI by via self-reported questionnaire Exclusion Criteria: 1. For patients who will be receiving a tracer injection, no known allergy to the imaging agents 2.

1. Informed consent will be obtained before beginning any study procedures. 2. Participants will receive a small quantity of an FDA approved radiotracer. The PET insert is placed within a 3T MRI scanner, where PET and MRI imaging will be completed.
