SGH unveils new imaging technique to detect rare pancreatic tumours

Exendin-4 imaging highlights tumours as distinct bright spots during PET/CT scans.

Singapore General Hospital (SGH) has introduced a new imaging technique that enhances the detection of insulinomas, rare pancreatic tumours that can be difficult to locate using conventional scans.

The exendin-4 imaging technique, tagged with a radioactive material through a specialised radiolabelling process, highlights tumours as distinct bright spots during Positron Emission Tomography/CT scans.

The enhanced imaging supports more accurate diagnosis and localisation, said Huang Hian Liang, Senior Consultant at SGH’s Department of Nuclear Medicine and Molecular Imaging.

“By improving tumour localisation, we can offer patients more targeted and potentially minimally invasive treatment options,” Huang added.
