New PET scan tracer could shine a light on hidden pancreatic tumors

NCT ID NCT07340437

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a new radioactive tracer called 18F-Exendin-4, used with PET/CT scans, to see if it can better detect insulinoma—a rare tumor in the pancreas that causes dangerously low blood sugar. Twenty participants with confirmed insulinoma received the tracer and underwent imaging. The goal was to compare the scan results with standard tests like MRI and CT. If the new method proves accurate, it could offer a less invasive way to diagnose these tumors.

What this could mean

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

Active substance
18F-Exendin-4 (a radioactive tracer for PET/CT imaging)
What this could lead to
If successful, this imaging method could provide a more accurate, non-invasive way to detect insulinoma, potentially reducing the need for exploratory surgery.
What could go wrong
This is a small, early-stage study with only 20 participants, so results may not apply to everyone. The probe's accuracy and safety need further validation in larger trials.
