NCT04383808

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • PETMR image

    The key specific measurement is the resulting PET/MR image obtained from the single subject scan.

    Up to 24 months

Study Arms (2)

Arm-1

EXPERIMENTAL

20 participants will be recruited, inject with radiopharmaceutical, and imaged on the 3T PETMR with PET insert.

Diagnostic Test: Injected radiotracer with PET Insert

Arm-2

EXPERIMENTAL

20 participants will be recruited from other imaging studies that have been already injected (pre-injected) with a radiopharmaceutical. These subjects wont receive an additional injection of radiopharmaceutical.

Diagnostic Test: Pre-injected group with PET insert

Interventions

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.

Arm-1

1. Informed consent will be obtained before beginning any study procedures. 2. Participants who have received radiotracer for another PET imaging system. The PET insert is placed within a 3T MRI scanner, where PET and MRI imaging will be completed.

Arm-2

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Whole body radiation dose within the last year of less than 5000 mrem

  • Subjects will be at least 21 years of age
  • Subject provides written informed consent
  • Subject is deemed healthy by the PI by via self-reported questionnaire

You may not qualify if:

  • For patients who will be receiving a tracer injection, no known allergy to the imaging agents
  • Participant has a history of or current diagnosis of cancer
  • Participant is pregnant or nursing
  • Metallic implants (contraindicated for MRI)
