title: Early and Delayed 18F-FCH PET/CT Imaging in Parathyroid Adenomas.
abstract: Preoperative localization with Tc-sestaMIBI or ultrasound is a common prerequisite for successful minimally invasive parathyroid adenoma (PA) surgery. SPECT/CT with Tc-sestaMIBI and PET/CT with F-FCH offer the possibility of attenuation correction and coregistration of functional and anatomical images providing more accurate PA localization. F-FCH PET/CT is used predominantly in patients with prostate cancer and is under investigation in PA. We report the case of a 43-year-old man with early FCH uptake in a cystic PA with delayed washout at 60 minutes.
