• 18F-fluorocholine (FCH) has been used as a positron emission tomography (PET) tracer in the localization of hyper-functioning parathyroid glands (HPGs). We performed this methodological study to evaluate the diagnostic performance of 18F-FCH PET/computerized tomography (CT) and repeated ultrasonography (USG) in detecting unidentified lesions in patients with primary hyperparathyroidism (PHPT). In this retrospective methodological study, we studied the diagnostic performance of 18F-FCH PET/CT and a repeated USG in detecting unidentified parathyroid lesions. Twenty-eight patients who were diagnosed with PHPT, had an indication for surgery following the current guidelines and had no identified lesion on 99mTc-MIBI SPECT/CT, USG, or other imaging methods than 18F-FCH PET/CT, included in the study. While lesions were detected in 26 patients 18F-FCH PET/CT among 28 patients [92.9% (95% CI: 76.6%-99.1%)], the lesion detection rate was 95.7% (95% CI: 78.1%-99.9%) in 23 patients who underwent a repeated USG. The sensitivity and the accuracy of both 18F-FCH PET/CT and repeated USG were 95.2% (95% CI: 76.2%-99.9%) and 95.0 (95% CI: 75.1%-99.9%), respectively. This study supports that the combination of 18F-FCH PET/CT and repeated USG has promising potential for being an imaging technique for early detection and localization of HPGs.
