New PET scan to detect tumor regrowth vs. scar tissue in brain
Part of Brain & nervous system, Cancer clinical trials.
This study tests a new type of PET scan (a special imaging test) that uses a radioactive tracer to help doctors tell the difference between scar tissue from past radiation and cancer that has come back in the brain. This could help avoid unnecessary surgery or additional treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older
- You have cancer that has spread to the brain (lung, melanoma, or breast cancer), OR you had brain metastases treated with radiation at least 9 months ago, OR doctors are unsure if a brain lesion is scar tissue or recurrent cancer
- You have a measurable brain lesion at least 10mm in size
- You are in good enough health to tolerate the scan (WHO performance status 0–3)
- You are not pregnant and have no known allergy to the Ga68-PSMA tracer
- You have not had a seizure in the last 7 days and your life expectancy is at least 3 months

Other trials that look related to this one.
This trial tests a special imaging scan called Ga-68 PSMA-11 PET/CT to see if it can better detect when a glioma brain tumor has come back or progressed. It is for people who have already had standard treatment and are planning surgery for a suspected recurrence.
This Phase 1 study tests whether a specialized PET scan tracer can “light up” metastatic non-small cell lung cancer in the brain. If you join, you’ll get brain MRI and PET/CT scans and you’ll continue with your planned cancer treatments and follow-up imaging.
This study tests a new type of PET/CT scan that uses a special tracer (68Ga-MY6349) to better see prostate cancer in the body. It may help doctors find cancer that has come back or spread, so you can get the right treatment sooner.
This trial tests if a special scan (PSMA-PET) can help plan surgery for melanoma that has spread to lymph nodes. It may help doctors remove all cancer more accurately.
This study looks at how well a special scan (PSMA PET/CT) works for people with cancers other than prostate cancer. If your doctor already scheduled this scan for your care, you may be able to help researchers learn more about its accuracy.
This study tests a new type of PET scan (a detailed imaging test) to find out if prostate cancer has come back after treatment. You'll receive an injection of a special tracer and then have a scan that takes pictures to help doctors locate any cancer.
