Popis: Summary:Preoperative localization of parathyroid adenomas (PA) can shorten operation time and improve curative rate; it becomes especially important in minimally invasive surgical techniques. Aim of this study was to investigate whether positron emission tomography (PET) with 3-,4-dihydroxy- 6-18F-fluorophenylalanine (18F-DOPA), which showed very promising results in other neuroendocrine tumours, also helps to localize PA. Patients, methods: Eight patients with proven primary hyperparathyroidism were studied preoperatively with PET. Seven also underwent scintigraphy with 99mTc-MIBI and ultrasonography of the neck. All patients were operated and the histological finding was used as a gold standard. Results: All eight patients had a histologically proven PA. None of the PA showed any detectable uptake of 18F-DOPA. However, ultrasonography detected 5/7 PA, scintigraphy detected 3/7 PA. Conclusion: These results suggest that PET with 18F-DOPA is not useful in the detection of PA in patients with primary hyperparathyroidism.
