Objective: Primary hyperparathyroidism is a common endocrine disorder, with 80% of all cases usually caused by one single hyperfunctioning parathyroid adenoma. Conventional imaging modalities for the diagnostic work‐up of primary hyperparathyroidism (PHPT) include ultrasound of the neck, 99mTc‐sestamibi scintigraphy, and four‐dimensional computed tomography (4D‐CT). However, the role of other imaging modalities, such as 11C‐methionine PET/CT, in the care pathway for PHPT is currently unclear. Here, we report our experience of the diagnostic utility of 11C‐methionine PET/CT in a single‐center patient cohort (n = 45). Design: Retrospective single‐center cohort study. Patients and Measurements: The data of eligible patients that underwent 11C‐methionine PET/CT between 2014 and 2022 at Addenbrooke's Hospital (Cambridge, UK) were collected and analyzed. The clinical utility of imaging modalities was determined by comparing the imaging result with histopathological and biochemical outcomes following surgery. Results: In patients with persistent primary hyperparathyroidism following previous surgery, 11C‐methionine PET/CT identified a candidate lesion in 6 of 10 patients (60.0%), and histologically confirmed in 5 (50.0%). 11C‐methionine PET/CT also correctly identified a parathyroid adenoma in 9 out of 12 patients (75.0%) that failed to be localized on other imaging modalities. 11C‐methionine PET/CT had a sensitivity of 70.0% (95% CI 55.8 – 84.2%) for the detection of parathyroid adenomas. Conclusions: This study highlights a diagnostic role for 11C‐methionine PET/CT in patients that have undergone unsuccessful prior surgery or have equivocal or negative prior imaging results, aiding localization and a targeted surgical approach.
