IMAGING MODALITIES IN THE EVALUATION OF P RIMARY HYPERPARATHYROIDISM

The results of several imaging modalities for the evaluation of parath yroid adenoma in patients with primary hyperparathyroidism are present ed. Different modalities (sonography, magnetic resonance tomography, c omputerized tomography, thallium-technetium-subtraction-scintigraphy) were performed in urinary stone patients after establishing the diagno sis by repeated measurements of serum calcium and serum parathyroid ho rmone. Sonography showed the best diagnostic efficacy (64 %). By combi ning different imaging modalities a diagnostic efficacy of 90 % was ac hieved. It is concluded that an interdisciplinary evaluation in patien ts with proven hyperparathyroidism should be initiated by the urologis t and thyroid exploration should be recommended to the patient.
