A Study of [13C]Pyruvate as an Imaging Agent for Magnetic Resonance Imaging in Healthy Volunteers
September 26, 2023 updated by: Memorial Sloan Kettering Cancer Center
Optimized In-Human [13C]Pyruvate MRI For Assessment Of Physiologic Reference Data In Different Organs
The purpose of the study is to learn about the use of [13C]pyruvate as an imaging agent for MRI scans.
In past studies, researchers have seen that [13C]pyruvate can improve imaging with MRI scans.
However, they would like to know more about how the imaging agent is distributed in healthy organs and tissues.
This study will provide additional information about the use of [13C]pyruvate as an imaging agent for MRI scans, and it will show us how the substance is metabolized (changed into energy) in the organs and tissues of healthy volunteers.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
18 years to 80 years (Adult, Older Adult)
Accepts Healthy Volunteers
Yes
Description
Inclusion Criteria:
Fifty healthy volunteers will be included.
- Age between 18-80
- Negative serum or urine pregnancy test for female volunteers of childbearing age and potential (as defined by MSKCC Standards & Guidelines), from assays obtained <2 weeks prior to study enrollment. Urine pregnancy tests are only valid for the day of test.
Exclusion Criteria:
- Breast-feeding
- History of metabolic (e.g. diabetes) and renal functional disorders.
- Refusal or inability to tolerate the scanning procedure (e.g., due to claustrophobia)
- Acute major illness (e.g., unstable cardiovascular condition, systemic malignant diseases, etc.).
- Standard MRI safety screening will be applied (MRI screening questionnaire); volunteers with MR unsafe devices, or conditional devices where research mode is not allowed, will be excluded.

---|---|
Experimental: Protocol optimization cohort
Following the [13C]pyruvate injection, dynamic imaging and 3D volumetric imaging of volunteers in the first cohort (HP MRI protocol optimization, Aim 1) will be performed on the 3-T MRI scanner, using different [13C] RF excitation/detection coils.

Will be injected at a dosage of 0.43 ± 0.05 mL/kg body weight

Experimental: Tissue reference cohort
The optimal setup will then be used for HP MRI of the second cohort.
