The Utility of 18F-fluorocholine PET/CT in the Imaging of Parathyroid Adenomas

September 25, 2020 updated by: Andrzej Mazurek, Military Institute of Medicine, Poland
We assessed sensitivity of 18F-FCH PET/CT in preoperative localisation of hyperfunctioning parathyroid tissue in patients with primary hyperparathyroidism (PHPT).

Detailed Description

We prospectively enrolled 65 consecutive patients with PHPT who underwent neck ultrasound (US) and parathyroid scintigraphy (99mTc/99mTc-MIBI dual phase). Twenty-two patients had unsuccessful parathyroid surgery prior to the study. PET/CT scans were performed 65.0 ± 13.3 min after injection of 218.5 ± 31.9 MBq of 18F-fluorocholine (FCH). Three experienced nuclear medicine physicians assessed the detection rate of hyperfunctioning parathyroid tissue. Response to parathyroidectomy and clinical follow-up served as a reference test. Per-patient sensitivity and positive predictive value (PPV) were calculated for patients who underwent surgery.
