BACKGROUND AND OBJECTIVES: In primary hyperparathyroidism (pHPT) preoperative localization of parathyroid adenomas enables focussed unilateral parathyroidectomy. Ultrasound and sestamibi scintigraphy are the recommended standard procedures for primary diagnostics of pHPT and C-11 methionine positron emission tomography computed tomography (Met-PET/CT) is the latest technique for localization of hyperfunctioning parathyroid glands.
METHODS: This review presents the results of Met-PET/CT on the basis of a selective literature search using the keywords "primary hyperparathyroidism and methionine", "primary hyperparathyroidism and PET", "parathyroid adenomas and methionine" and "parathyroid adenomas and PET".
RESULTS: Localization of single gland adenomas can be achieved with Met-PET/CT in 79-91 % of cases. The advantages of this procedure are a high sensitivity even in operations for recurrencies or concomitant thyroid nodules and an accurate detection even with atypical localizations. In multiglandular disease a localization of more than one hyperfunctioning gland remains difficult. Potential limitations of the method include the restricted availability and the relatively high costs of Met-PET/CT.
CONCLUSIONS: Using Met-PET/CT hyperfunctioning parathyroid glands can be exactly localized in most patients with pHPT. Indications for this procedure are mostly when preoperative standard tests are negative and in parathyroid surgery for recurrencies.
