Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 30-80 years with clinically diagnosed pheochromocytoma who can provide informed consent.

Probably not a fit

Patients with serious primary diseases, uncontrolled hypertension, or contraindications to PET imaging may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to assess the diagnostic performance and tumor burden of 18F-metafluorobenzylguanidine (18F-MFBG) positron emission tomography (PET) in patients diagnosed with pheochromocytoma. It focuses on the advantages of 18F-MFBG over traditional imaging methods, particularly its ability to provide better image quality and quicker imaging times. Patients with suspected or confirmed pheochromocytoma will be enrolled, and the study will evaluate the safety profile and effectiveness of this imaging technique. The goal is to improve diagnostic accuracy and facilitate better clinical management of the condition.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy for pheochromocytoma, enabling better treatment planning for patients.

How similar studies have gone: Preliminary data suggest that 18F-MFBG imaging has shown promise, indicating potential success in this novel approach.
