New scan could spot parathyroid tumors that old tests miss
NCT ID NCT05891769
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a newer PET scan using 18F fluorocholine can find parathyroid adenomas that standard SPECT/CT scans miss. About 100 adults with high calcium and negative or unclear standard scans will receive the new scan. The goal is to see if the new method detects more adenomas, which could help guide surgery and improve outcomes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- 18F fluorocholine
- What this could lead to
- If successful, this could offer a more accurate way to spot parathyroid adenomas, helping more patients get the right surgery without unnecessary neck exploration.
- What could go wrong
- This is a small, early-phase study (Phase 2/3) with only 100 participants. The new scan may not find more adenomas than the standard test, and false positives could lead to unnecessary procedures.
