PRIMARY OBJECTIVE:~I. To investigate the performance (accuracy) of 18F-fluorocholine PET in the detection of hyperfunctioning parathyroid glands in surgical patients with biochemically proven primary hyperparathyroidism.~OUTLINE:~Participants will receive a single dose of 18F-Fluorocholine at the time the participant undergoes a single imaging study using 18F-fluorocholine. Study related procedures will end after the study visit. Participants who undergo subsequent parathyroidectomy, will have the results reviewed and compared to the results from the imaging study
This is a prospective single arm single center Phase III study evaluating the ability of 18F-fluorocholine to detect the location of parathyroid adenomas.
