Study Summary

This is a prospective single arm single center Phase III study evaluating the ability of 18F-fluorocholine to detect the location of parathyroid adenomas.

Primary Outcome

Sensitivity of 18F-fluorocholine PET for the detection of abnormal parathyroid adenomas confirmed by pathology as compared to sestamibi imaging. Location of parathyroid adenoma at imaging as read by three blinded readers, will be correlated to the location at surgery. True positive will be defined as an adenoma on imaging in the same location as seen at surgery. Sensitivity will be reported by individual reader.
