Assessing pancreatic beta cell mass and function in diabetes using PET imaging
Official title: Assessment of Pancreatic Beta Cell Mass and Function with the Aid of Positron Emission Tomography Imaging in Human Diabetes Mellitus
Run by Azienda Ospedaliero-Universitaria di Parma · NCT05662189 · Data updated 2026-11-12
This study is testing a new imaging tool to see how well the insulin-producing cells in the pancreas are working in people with type 1 and type 2 diabetes, as well as those with prediabetes.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 to 75 with type 1 or type 2 diabetes, prediabetes, or hyperinsulinism who are in good health.
✕Probably not a fit
Patients with severe kidney or liver disease, active malignancies, or those on medications affecting beta cell function may not benefit from this study.

What this trial studies
This project aims to develop a novel tool for evaluating pancreatic beta cell mass (BCM) and function (BCF) in individuals with type 1 and type 2 diabetes, as well as prediabetes and hyperinsulinism. By utilizing 68Ga-exendin-4 and advanced PET imaging techniques, the study seeks to measure beta cell functional mass (BCFxM) in vivo, providing insights into the pathogenesis of diabetes. The research will involve participants undergoing a mixed meal test alongside PET imaging to assess their beta cell activity and health.
Why it matters
Potential benefit: If successful, this study could lead to improved diagnostic methods for assessing beta cell function and mass, ultimately enhancing diabetes management.
How similar studies have gone: While the approach of using PET imaging for assessing beta cell function is innovative, similar methodologies have shown promise in other studies, indicating potential for success.
