Recruiting studies
- NCT01730781Recruiting
PET scan study to image cannabinoid receptors in the brain
This study uses a special brain scan (PET) to measure cannabinoid receptors—areas in the brain that interact with cannabis-like chemicals. It may help researchers better understand how these receptors relate to conditions such as schizophrenia, PTSD, opioid use disorder, or early psychosis risk.
New Haven, ConnecticutAges 18–55 - NCT03321045RecruitingEarly Phase 1
PET scan to predict benefit from HER2-targeted breast cancer therapy
This early-phase study uses a special PET scan with a drug tagged for imaging to predict how well HER2-targeted treatments will work. It may help doctors choose the most effective therapy for HER2-positive breast cancer.
Birmingham, AlabamaAges 18 years+ - NCT07419178Recruiting
New scan test for scarring in blood cancers
This study tests a new way to detect scar tissue in the bone marrow using a special scan and blood test. It might help doctors see how your disease is changing without needing a bone marrow biopsy.
Parma, ItalyAges 18 years+ - NCT07457736RecruitingEarly Phase 1
Testing a new imaging agent for the brain
This study tests a new radioactive dye called [18F]GATT-44 to see how well it can show a specific brain protein on a PET scan. It may help researchers better understand brain conditions in the future.
New Haven, ConnecticutAges 18–60 - NCT07463625Recruiting
PET scan for finding ACTH-secreting pituitary tumors
This trial tests a special PET scan using a tracer called FET to locate tiny ACTH-producing pituitary tumors (microadenomas) causing Cushing's disease. It might help guide surgery by identifying exactly where the tumor is in the gland.
BronAges 18 years+ - NCT07488819Recruiting
Brain imaging study for people with PTSD or alcohol use disorder
This study uses a special brain scan (PET) to look at a protein called PDE4B in people with PTSD or alcohol use disorder. It may help researchers understand these conditions better.
New Haven, ConnecticutAges 18–70 - NCT07548099Recruiting
PET scan study of aorta inflammation in aneurysm patients
This research uses a special imaging scan (PET/CT) to take detailed pictures of inflammation in the aorta (the main blood vessel from your heart). Researchers want to understand why some people develop bulges in their aorta called aneurysms. If you have an aneurysm or are a healthy volunteer, this study may help improve how doctors detect and treat this condition.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07567196Recruiting
PET imaging to guide surgery for aggressive brain tumors
This trial tests whether using a special PET scan (a type of imaging that shows tumor activity) during brain tumor surgery helps doctors remove more of the tumor safely. You would have a high-grade glioma (an aggressive brain cancer) and be scheduled for surgery.
Torino, TurinAges 18 years+ - NCT07617688RecruitingEarly Phase 1
PET imaging tracer safety study in healthy volunteers
This early-stage study tests a new PET imaging agent (a radioactive tracer used in medical imaging) to understand how it moves through the body and the radiation dose it delivers. Researchers need healthy volunteers to help establish whether this imaging tool is safe for future patient use.
New Haven, ConnecticutAges 18–60 - NCT07041372Enrolling by invitation
Brain PET Study for Recent Stroke Patients
This study uses a special brain scan (PET) to learn more about how artery hardening (atherosclerosis) affects stroke. It is for people who have just had a stroke and may help doctors understand the disease better.
Seoul, Jong-ro GuAges 19 years+ - NCT06821646Enrolling by invitation
Brain responses in depression and autism with TMS and EEG
This study uses brain stimulation (TMS) and brain wave recording (EEG) to understand how the brain works in people with autism, depression, or both. It may help find better ways to treat these conditions.
TaipeiAges 20–50 - NCT06044324Enrolling by invitation
Imaging brain activity in TMS for depression
This trial uses PET scans to see how transcranial magnetic stimulation (TMS) affects the brain in people whose depression hasn't improved with at least two different antidepressants. It aims to find markers that could predict who might benefit from TMS.
Hangzhou, ZhejiangAges 18–45 - NCT05530356Enrolling by invitation
Study of kidney blood flow and insulin resistance in youth
This study looks at how well insulin is working and how the kidneys use energy by measuring kidney blood flow. It compares obese young people with and without type 2 diabetes to lean controls, using a PET scan (a special imaging test).
Aurora, ColoradoAges 12–26 - NCT04482660Enrolling by invitation
PET brain scan study of tau protein in ALFA volunteers
This study uses a special PET brain scan tracer to measure “tau” protein clumps in the brain. It’s meant to better understand brain changes in people who are already part of the ALFA research program, and may help researchers connect tau levels with memory and thinking.
Barcelona, BarcelonaAges 45 years+ - NCT06716294Recruiting
Radiofrequency ablation and stabilization for spine tumors
This trial tests a treatment that uses heat to destroy active spine tumors from cancer that has spread, followed by stabilizing the bone. It aims to see if the treatment works by using a special scan (PET-CT) to confirm the results.
Athens, AthensAges 18–90 - NCT04989959RecruitingPhase 1
PET/CT scan test in kidney cancer and related conditions
This Phase 1 study tests whether a special PET/CT scan drug ([18F]PT2385) can help doctors see kidney cancer and related tumors. It may help guide diagnosis and treatment decisions, especially in people planning surgery or starting belzutifan.
Dallas, TexasAges 18 years+ - NCT06067503RecruitingPhase 2
PET scan to detect hormone therapy resistance in breast cancer
This trial tests a new PET scan (called FFNP) to see if it can find which breast cancers stop responding to hormone therapy early. It's for people with advanced hormone-receptor-positive breast cancer who are starting a new endocrine treatment.
Madison, WisconsinAges 18 years+ - NCT06199713Recruiting
Melanoma trial tracking treatment response with PET scans and blood tests
This study is looking at whether a special PET scan (FDG PET/CT) and a blood test that measures ctDNA (cancer DNA in the blood) can help predict how well immune checkpoint inhibitors work in people with advanced melanoma. If you are planning to get treatment with immunotherapy drugs like ipilimumab, nivolumab, or pembrolizumab, you may be able to join.
Madison, WisconsinAges 18 years+ - NCT06204237RecruitingEarly Phase 1
PET imaging safety study for leg artery disease patients and healthy volunteers
This study tests whether a new radioactive tracer called APAC is safe and can be seen in PET/CT scans. It is for people with blocked leg arteries (PAOD/CLI) and for healthy volunteers. The goal is to see where the tracer goes in the body and how the body tolerates it.
GroningenAges 40–85 - NCT04857502RecruitingEarly Phase 1
Tracking prostate cancer spread before lymph node surgery
This early study uses a special imaging tracer to show where prostate cancer has spread in the pelvic lymph nodes. It may help doctors better understand how well certain scans guide surgical removal of affected lymph nodes.
Los Angeles, CaliforniaAges Any age - NCT07309107Recruiting
Deep learning study of amyloid pet scans for memory issues
This trial is testing a deep learning tool on amyloid PET scans from patients with memory problems. It aims to improve diagnosis and understanding of Alzheimer's disease.

Common questions
- Are there clinical trials for positron emission tomography?
- Yes. Clin2 currently lists 357 recruiting positron emission tomography 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 positron emission tomography 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 positron emission tomography 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.
