Abstract
Purpose
Preoperative localization of a parathyroid adenoma is usually obtained by the combination of ultrasound and scintigraphy with technetium-99m methoxyisobutylisonitrile. We evaluated the role of F18-fluorocholine in neck positron emission tomography/magnetic resonance imaging as a novel tool for localizing parathyroid adenomas.
Methods
Patients with primary hyperparathyroidism were recruited from February 2016 to August 2017 and F18-fluorocholine positron emission tomography/magnetic resonance imaging was performed to localize the parathyroid adenoma prior to surgery. We compared sensitivity and accuracy of this modality with ultrasound and technetium-99m methoxyisobutylisonitrile scintigraphy using the verified location of the diseased parathyroid as found in surgery.
Results
Nineteen patients were included in our study (15 women and 4 men, mean age 60.5 ± 9.8 years). Positron emission tomography/magnetic resonance imaging precisely localized the pathologic parathyroid gland in 16/19 cases (84.2%) and predicted the diseased side in 19/19 cases (100%). Ultrasound and technetium 99 m methoxyisobutylisonitrile sestamibi scintigraphy predicted the location of the parathyroid adenoma in 16/19 (84.2%) and 14/19 (74%), respectively. In 3/19 patients, positron emission tomography/magnetic resonance imaging localized the parathyroid adenoma where as other modalities failed. Positron emission tomography/magnetic resonance imaging was more accurate when compared to each modality separately (p < 0.001, p = 0.017), however, when comparing the three modalities all together no differences were found (p = 0.506).
Conclusions
Localizing parathyroid adenomas with F18-fluorocholine positron emission tomography/magnetic resonance imaging may be a promising secondary imaging modality.
