Radiology
Also Known As:
⁸F-fluorocholine (¹⁸F-FCH) PET/CT is increasingly used in parathyroid imaging, especially for primary hyperparathyroidism when standard imaging is inconclusive.
Standard imaging options:
¹⁹⁹mTc-sestamibi SPECT/CT
High-resolution neck ultrasound
However, these can be negative or discordant in up to 20–30% of cases.
Indications for ¹⁸F-fluorocholine PET/CT
Localization of hyperfunctioning parathyroid tissue in patients with primary hyperparathyroidism:
When first-line imaging (ultrasound and/or sestamibi) is negative, equivocal, or discordant.
To guide minimally invasive surgery.

Frequently Asked Questions
It is a combined scan that shows both structure and activity of organs.
¹⁸F-Choline PET/CT is a highly useful tracer for localizing hyperfunctioning parathyroid tissue, especially in difficult cases.¹⁸F-Choline PET/CT is now one of the best imaging modalities for parathyroid adenoma localization.
It is generally safe but can be potentially harmful, a small amount of radioactive tracer is used which leaves the body quickly.

TAT Policy
The Turnaround Time (TAT) for a test depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
Please note that in uncommon circumstances, TAT may be delayed due to the complexity of the test or reasons beyond our control. You will be informed about the estimated TAT at the time of registration or after completion of the test.
