Clinical applications of GLP-1 receptor–targeted PET imaging: A disease-oriented review

Surprising Findings
GLP-1 receptors are found in many tissues beyond the pancreas — including heart, kidneys, cartilage, and brain — and may play diverse roles.
Most people think of GLP-1 as only a gut hormone involved in blood sugar and appetite, but it appears to have widespread effects across the body.
Practical Takeaways
Patients with suspected insulinomas may benefit from GLP-1R PET imaging where available, as it offers high sensitivity for tumor detection.

Your body has special switches called GLP-1 receptors not just in your gut and pancreas, but also in your heart, brain, kidneys, and even cartilage — and they help control different body functions in all those places.
A special kind of body scan using a tagged molecule might help doctors find tiny tumors in the pancreas that cause low blood sugar — all without surgery.
A special kind of body scan might help doctors tell the difference between when insulin-making cells in the pancreas are gone versus just not working right — without needing surgery — which could help better manage diabetes.
If someone has obesity, their body might have fewer GLP-1 receptors. A special scan could help doctors see if those receptors come back after treatment with certain weight-loss drugs or surgery.
A special kind of body scan using a radioactive tag might help scientists see how insulin-making cells change in people with diabetes or obesity, which could help in developing new treatments.
