Clinical Translation of a Novel Brain PET Insert for Simultaneous PET/MR
What this study is about
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.

Interventions
DIAGNOSTIC_TEST
Injected radiotracer with PET Insert
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.
DIAGNOSTIC_TEST
Pre-injected group with PET insert
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.
Primary outcome measures
PETMR image
Time frame: Up to 24 months
The key specific measurement is the resulting PET/MR image obtained from the single subject scan.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

- 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
Exclusion criteria
- 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)
Where
- Palo Alto, California

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
