Using 18F-Fluorocholine PET to find parathyroid adenomas

18F-Fluorocholine Positron Emission Tomography (PET) for the Detection of Parathyroid Adenomas

Phase 3 Interventional University of California, San Francisco · NCT04895631

This study is testing if a special imaging technique using 18F-fluorocholine can help find overactive parathyroid glands in people with primary hyperparathyroidism before they have surgery.

What this trial studies

This Phase III study evaluates the effectiveness of 18F-fluorocholine positron emission tomography (PET) in locating hyperfunctioning parathyroid glands in patients with primary hyperparathyroidism. Participants aged 13 and older with biochemically confirmed hyperparathyroidism will receive a single dose of 18F-fluorocholine during an imaging study. The results from the imaging will be compared to findings from subsequent parathyroid surgery to assess accuracy. This single-center study aims to improve detection methods for surgical candidates.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 13 and older with biochemically proven primary hyperparathyroidism who are indicated for surgery.

Not a fit: Patients who are currently pregnant or those deemed unsuitable for study participation by the investigator will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of locating parathyroid adenomas, leading to better surgical outcomes for patients.

How similar studies have performed: Other studies using PET imaging for similar purposes have shown promising results, indicating potential success for this approach.
