Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only

Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Summary

This study will compare two types of PET scans (using different radioactive tracers) in 6 adults with suspected meningioma who are scheduled for surgery. Each person will get both scans at least 24 hours apart. The goal is to see which tracer gives clearer images of the tumor, which could help doctors better diagnose and plan treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Ga-68-DOTATATE and Ga-68-DOTATOC (radioactive tracers for PET scans)
What this could lead to
If successful, this could help determine which tracer is better for detecting meningioma, potentially improving diagnosis and treatment planning.
What could go wrong
This is a very small, early-phase study with only 6 participants, so results may not apply to everyone. It focuses on imaging comparison, not treatment.
