PET/CT scan testing a new radioactive tracer for tumors
This early-phase study uses PET/CT scans to see how well a new radioactive tracer (a tiny dose of a special material) highlights solid tumors in the body. It may help researchers learn whether this tracer can better find and track tumor spots seen on standard scans.
Houston, TexasAges 18 years+ - NCT03622359Recruiting
Imaging blood flow in leg artery disease using a scan
This study uses a special “radiotracer” scan to look at how well blood flows through the arteries in the legs. It may help researchers better understand circulation problems from peripheral artery disease.
Columbus, OhioAges 18 years+ - NCT04038840RecruitingPhase 1
Brain PET-MR imaging to study schizophrenia connections
This early (Phase 1) study uses a special brain scan to look at synapses—the contact points between brain cells—in people with schizophrenia-related conditions. It helps researchers understand brain activity and connection patterns, which may guide future tests or treatments.
Palo Alto, CaliforniaAges 18–65 - NCT04383808Recruiting
PET/MRI scan with a small injected tracer
This study tests a new brain PET “insert” that can work at the same time as MRI to create brain images. If you’re healthy and can receive an approved injected tracer (FDG or Neuraceq), you may be able to help confirm the device works safely and clearly.
Palo Alto, CaliforniaAges 21 years+ - NCT04532489RecruitingEarly Phase 1
PET scan study using a cholesterol-tracking tracer in healthy adults
This early study tests how well a special PET scan tracer can show cholesterol movement in the body. It is for healthy adults who do not have known adrenal problems, and it aims to collect basic imaging safety and dose information.
Ann Arbor, MichiganAges 18 years+ - NCT04546126RecruitingEarly Phase 1
PET scan study tracking cholesterol movement in your body
This early study uses a special PET scan dye to see how cholesterol moves through the body. It is testing how the imaging works in healthy people and in people with adrenal gland hormone secretion problems, to better understand cholesterol handling.
Ann Arbor, MichiganAges 18 years+ - NCT05231798RecruitingPhase 2
PET and brain scans in adults with Down syndrome
This study looks at how well a brain chemical system works in adults with Down syndrome as they age, including how it relates to Alzheimer’s-type brain changes and thinking skills. It uses brain scans and memory/thinking tests to see whether these measures can help track risk or changes over time.
Nashville, TennesseeAges 18–55 - NCT05554302RecruitingPhase 2
PET scan study for brain metastases after surgery
This trial studies how well a special PET scan tracer (18F-fluciclovine) shows amino-acid changes in brain metastases after they are surgically removed. It may help improve how doctors detect and understand brain metastases and guide follow-up treatment like targeted radiation (SRS).
Miami, FloridaAges 18 years+ - NCT05582876Recruiting
PET/MR scan to plan personalized prostate cancer treatment
This study uses a special scan called PET/MR with a prostate-focused tracer to help doctors choose the best next treatment for prostate cancer. It may be most helpful if you are planning major treatment or if your cancer has come back after prior treatment.
BialystokAges 18–99 - NCT05630963Recruiting
Study sleep-like brain signaling in major depression
This trial looks at how a specific brain receptor related to pain signals (nociceptin/orphanin FQ receptor) may be involved in depression. It may help researchers understand depression better by comparing people with current versus past (remitted) major depression.

Créteil, Île-de-France RegionAges 18–65 - NCT05942716RecruitingPhase 2
Testing how serotonin changes impulsivity in Tourette
This Phase 2 study looks at whether changing serotonin activity can affect impulsivity and related brain function in people with Tourette disorder. You may be asked to continue aripiprazole and complete brain scans that test how your brain responds during tasks.

Common questions
- Are there clinical trials for radiotracer?
- Yes. Clin2 currently lists 33 recruiting radiotracer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a radiotracer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a radiotracer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
