Single-tracer Multiparametric PET Imaging
What this study is about
The overarching goal of this project is to develop and evaluate a single-tracer multiparametric positron emission tomography (PET) imaging solution for simultaneous imaging of blood flow and glucose metabolism using 18F-fluorodeoxyglucose (FDG) alone.
View original scientific description
The overarching goal of this project is to develop and evaluate a single-tracer multiparametric positron emission tomography (PET) imaging solution for simultaneous imaging of blood flow and glucose metabolism using 18F-fluorodeoxyglucose (FDG) alone. The investigators working hypothesis is that quantitative blood flow can be extracted from dynamic 18F-FDG PET data by use of tracer kinetic modeling, in addition to glucose metabolism that 18F-FDG is conventionally used for.
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
- Adults (age ≥ 18 years old)
- Ability to understand and willingness to sign an informed consent form
- Ability to adhere to the study visit schedule and other protocol requirements.
- Willing and able to fast for at least 6 hours before and for the duration of the scan
- No strenuous exercise for 24 hours prior to being scanned
- Willing to lie on the scanner bed for up to 60 minutes
- Free of active COVID-19 symptoms
- Patients with clinically acute or chronic conditions such as cardiovascular, cardiometabolic, or cardiopulmonary diseases, which may include but are not limited to ischemic heart disease, myocarditis, arrhythmias, heart failure, nonalcoholic fatty liver disease, COVID-related sequala, diabetes, hypertension, or renal disease that would result in changes in normal tissue perfusion and/or metabolism.
Exclusion criteria
- Participants are not eligible if they meet ANY of the following criteria:
- Self-reported history of dysphoria or anxiety in closed spaces
- Body weight \>240 kg due to limitations of the scanner bed
- Pregnant or breast-feeding (due to risks of ionizing radiation; urine pregnancy test will be administered prior to start of each PET/CT session for all participants between 18 to 60 years old who are able to get pregnant, unless documented hysterectomy or bilateral ovarian removal is available)
- Blood glucose greater than 200 as assessed by fingerstick method before injection of 18F-FDG
- Concurrent or prior enrollment in a separate research study involving a PET scan performed within the last 12 months for research purposes only.
- Any condition that would prevent the understanding or rendering of informed consent.
- Any comorbidity that, in the opinion of the investigator, could compromise protocol objectives.
Where
- Sacramento, 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.
