Rare & Research Tracers
68Ga-Exendin-4, 68Ga-Trivehexin, and othersProtocol-dependentAdvanced molecular study
In simple words
Some tumours have their own unique signature. Insulin-producing tumours of the pancreas, for example, can be as small as a grain of rice and invisible on CT — but they carry GLP-1 receptors, which the Exendin-4 tracer is built to find. These studies are arranged case by case after discussion with your treating doctor.
Questions this scan answers
- I have unexplained low blood sugar attacks — where is the insulinoma?
- Is there a targeted tracer better suited to my specific tumour type?
The Prismaa difference
Dr. Keyur Mandaliya has hands-on reporting experience with Exendin-4 and Trivehexin studies, which very few centres in the region can say.
Usually recommended for
- Suspected insulinoma / nesidioblastosis with recurrent hypoglycaemia
- Selected αvβ6-integrin-expressing tumours
- Complex cases discussed in a tumour board where standard tracers fell short
How to prepare
- Protocols differ by tracer — our team will brief you in detail when the scan is scheduled.
- These tracers are produced to order, so booking usually needs a few days' notice.
