Purpose: Primary hyperparathyroidism is a common endocrine disorder which is diagnosed biochemically and for which therapy is surgical. A prerequisite for minimally invasive surgery, which minimizes morbidity and cost, is accurate localization of the involved gland(s). The aim of this study was to evaluate the usefulness of (18)F-fluorocholine PET/CT for preoperative localization of hyperfunctioning parathyroid tissue.
Methods: (18)F-Fluorocholine PET/CT and conventional parathyroid scintigraphic imaging consisting of (99m)Tc-sestaMIBI SPECT/CT, (99m)Tc-sestaMIBI dual-phase imaging and (99m)Tc-sestaMIBI/pertechnetate subtraction imaging were performed in 24 patients. The diagnostic performance of the imaging methods was compared against histology as the gold standard and postoperative serum Ca(2+) and iPTH values.
Results: The sensitivity and specificity of (18)F-fluorocholine PET/CT were 92% and 100%, respectively, in contrast to 49% and 100%, 46% and 100%, and 44% and 100% for (99m)Tc-sestaMIBI SPECT/CT, (99m)Tc-sestaMIBI/pertechnetate subtraction imaging and (99m)Tc-sestaMIBI dual-phase imaging, respectively. Combined conventional scintigraphic imaging had a sensitivity and specificity of 64% and 100%, respectively. The performance of (18)F-fluorocholine PET/CT was superior particularly in patients with multiple lesions or hyperplasia.
Conclusion: (18)F-Fluorocholine PET/CT appears to be a promising, effective imaging method for localization of hyperfunctioning parathyroid tissue.

Objective: To evaluate the correlation between response assessment measured by PET/CT with [F] F-fluorocholine (Choline PET/CT) and serum levels of PSA in patients with prostate cancer under antiandrogenic treatment.
Methodology: A retrospective study included patients with CRPC and CSPC treated with enzalutamide, abiraterone, or apalutamide between June 2018 and July 2021, who underwent baseline and a follow-up Choline PET/CT. The difference in maximum SUVmax (ΔSUV) between both studies and the PSA value before and at follow-up were recorded.

The standardization of preoperative imaging in primary hyperparathyroidism is one of the current challenges of endocrine surgery. A correct localization of the hypersecretory gland by neck ultrasound and 99mTc-sestamibi (MIBI) scintigraphy are not sufficiently sensitive in some cases. In recent years, CT-4D, 18F-Fluorocholine PET/CT, and radio-guided parathyroidectomy have come into common use.

Patients diagnosed with multiple endocrine neoplasia type-1 (MEN1) often initially present with primary hyperparathyroidism (pHPT), and typically undergo surgical intervention. While laboratory tests are fundamental for diagnosis, imaging is crucial for localizing pathological parathyroids to aid in precise surgical planning. In this pictorial review, we will begin by comprehensively examining key imaging techniques and their established protocols, evaluating their effectiveness in detecting abnormal parathyroid glands.
