18F-FluorThanatrace PET/CT for Pheochromocytoma and Paraganglioma

This study is looking at how a special imaging scan, called an 18F-FluorThanatrace (FTT) PET/CT, works in people with pheochromocytoma or paraganglioma. The scan uses a tracer, [18F]FTT, to show something called PARP-1 expression in your tumors. Researchers want to see if this scan can accurately measure PARP-1 in these tumors before you have surgery or other treatments. You would have this scan before your planned treatment. The study aims to enroll up to 30 adult patients who have been diagnosed with pheochromocytoma or paraganglioma and have at least one tumor visible on standard imaging.

Study design
This is an interventional study planning to enroll up to 30 participants. It is observational, meaning the scan results won't directly guide your treatment decisions.
What's involved
You would undergo an 18F-FluorThanatrace (FTT) PET/CT scan before surgery or systemic therapy. This involves an injection of [18F]FTT and approximately 60 minutes of dynamic scanning, followed by a second scan about 90 minutes later.
Compensation
Not stated in the trial record.
Follow-up
