Palo Alto, CaliforniaAges 18–65 - NCT04065321Recruiting
Blood test for tumor cells in certain early breast cancers
This trial looks at a blood test that may detect “circulating tumor cells” (cancer cells that can travel in the bloodstream) in people with a specific type of breast cancer. It may help doctors better track the disease and guide treatment for people whose tumors have certain hormone and growth-factor features.
Shenyang, LiaoningAges 18–60 - NCT04072653Recruiting
Sentinel node biopsy versus watchful waiting after PET
This trial studies whether taking a sample from the sentinel lymph node (a first lymph node that can be involved) improves care compared with observation, after a breast cancer PET scan of the armpit area. It may help people with certain early breast cancers avoid unnecessary procedures if the lymph nodes look negative on scans.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04081701RecruitingPhase 4
Ga-68 DOTATATE PET/MRI for somatostatin-receptor brain tumors
This trial tests how well a special scan (Ga-68 DOTATATE PET combined with MRI) helps diagnose and guide treatment for certain brain tumors that have somatostatin receptors. It may help doctors better find tumor recurrence or remaining tumor after treatment.
New York, New YorkAges 18–100 - NCT04086485RecruitingPhase 1/Phase 2
Lu-177 dotatate plus olaparib for inoperable neuroendocrine tumors
This study tests whether combining Lu-177 dotatate (a targeted radiation treatment) with olaparib (a targeted pill) can shrink or slow growth of inoperable gastroenteropancreatic neuroendocrine tumors. It’s designed for tumors that show the right “targets” on a special scan and that have started to progress despite standard care.
Bethesda, MarylandAges 18–100 - NCT04101968Recruiting
Study of GBA changes in Parkinson’s using multiple tests
This study looks at people with Parkinson’s who carry a specific genetic change in the GBA gene. It uses several tests (including brain scans) to understand the disease better and may help guide future treatments.
Portland, OregonAges 18–80 - NCT04235114RecruitingPhase 1/Phase 2
PET scan test for EGFR-positive cancers using an antibody tracer
This study tests a special PET scan agent (an antibody tracer) to help doctors see EGFR-positive cancers without needing invasive procedures. It is mainly for early testing (Phase 1/2) to understand how well it works for imaging.
Saskatoon, SaskatchewanAges 18–80 - NCT04271579Recruiting
Surgery for early prostate cancer spread seen on PSMA PET
This trial studies whether operating on a small, one-sided (unilateral) area of prostate cancer spread in the pelvic lymph nodes—found on a PSMA PET scan—can help control recurrence. It’s meant for people whose PSA is still low and whose spread appears limited on the scan.
HamburgAges 18–75 - NCT04362644RecruitingPhase 1
Imaging agent study for idiopathic pulmonary fibrosis lung scarring
This Phase 1 study tests a specialized imaging agent that can help show differences (heterogeneity) in lung scarring in idiopathic pulmonary fibrosis (IPF). It’s mainly about safety and whether the imaging works for people with certain genetic and lung-function features.
Birmingham, AlabamaAges 40–85 - NCT04396873RecruitingPhase 1
PET brain scan study of inflammation markers in neurodegeneration
This Phase 1 study tests a PET scan to measure inflammation-related changes in the brain using a medication called ketoprofen. It may help researchers understand which people with certain brain diseases could benefit from treatments aimed at inflammation.
Bethesda, MarylandAges 18–99 - NCT04412187Recruiting
Study of inflammation after a new stroke
This study looks at inflammation-related changes soon after an acute ischemic stroke (a type caused by a blocked blood vessel). It may help researchers understand what factors drive recovery and how they could be targeted in the future.
Munich, GermanyAges 50 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+ - NCT04537403RecruitingPhase 1
PET scan study of artery inflammation marker in plaque
This Phase 1 study tests whether a special PET scan can detect a specific inflammation signal (CCR2) in atherosclerosis—fatty plaque buildup in blood vessels. It may help future doctors better see which plaques are more inflamed and potentially more dangerous.
St Louis, MissouriAges 18–89 - 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+ - NCT04571086Recruiting
FAPI-PET scan to help find and stage tumors
This study uses a special PET scan (FAPI-PET) during routine workup to help detect tumors and decide how far they may have spread. You may be able to take part if you need a staging or restaging scan and can safely complete the imaging.
Essen, North Rhine-WestphaliaAges 18 years+ - NCT04612075Recruiting
PET-MR scan study for head and neck squamous cancer
This study uses a combined PET/MR scan to better look at head and neck squamous cell cancer before or during treatment. It may help doctors see where the cancer is and how far it has spread, to support planning for curative radiation treatment.
TromsøAges 18 years+ - NCT04621435RecruitingPhase 1
PET imaging test for solid tumors using FAP-2286
This Phase 1 study tests a special imaging scan (using FAP-2286) to see solid tumors in people who have already been diagnosed. It may help doctors better detect where cancer is in the body and how to plan treatment.
San Francisco, CaliforniaAges 18 years+ - NCT04642027RecruitingPhase 3
PSMA scan-guided salvage radiation after prostate surgery
This trial tests whether using a specialized PSMA PET scan to guide radiation can better treat prostate cancer that returns after prostate surgery. It targets the “prostate bed” area with a shorter, stronger radiation schedule (hypofractionated) to control rising PSA levels.
Arnhem, GelderlandAges 18–80 - NCT04706910RecruitingPhase 3
PET scan study to optimize imaging in several diseases
This trial improves a special PET scan (a type of brain/body imaging) using 18F-DOPA, to better show how certain conditions behave in the body. If you or your child may have one of the listed conditions, the study may help your doctors get clearer scan results.

- Are there clinical trials for pet?
- Yes. Clin2 currently lists 591 recruiting pet 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 pet 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 pet 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.
