Ultrasound and sestamibi scintigraphy are the recommended standard procedures for initial diagnosis in primary hyperparathyroidism (pHPT). Recently, F‑18 choline positron emission tomography computed tomography (choline PET/CT) has been shown promising results for the diagnostic work up of primary hyperparathyroidism (pHPT) suggesting superiority over conventional scintigraphy using Tc99m sestamibi based protocols using planar dual-phase imaging, SPECT or SPECT/CT.This review presents the results of F‑18 choline PET/CT on the basis of a literature search using the keywords "primary hyperparathyroidism and choline", "primary hyperparathyroidism and PET", "parathyroid adenoma and choline" und "parathyroid adenoma and PET".6 studies were identified dealing with the diagnostic impact of choline PET/CT. The studies included 5 to 151 patients. Localization of single gland adenomas can be achieved with choline PET/CT in 80 up to 96% of cases. A high sensitivity and accuracy of choline PET/CT imaging is documented even in cases of repeated surgery for recurrent pHPT, in coexistant nodular goiter or in the detection of adenoma in atypical localization.Using choline PET/CT parathyroid adenoma and probably parathyroid hyperplasia can be exactly localized in most patients with pHPT. Thus, a minimal-invasive surgical procedure is feasible with decreased risk of complications but high success rate in terms of biochemical cure. The diagnostic accuracy in multiglandular disease remains to be established.
