Abstract

Between 1992 and 1996, 31 cases (8 men and 23 women) with primary hyperparathyroidism (PHPT) were treated in our department.In this study, we compared which of the preoperative localization methods was most useful in the detection of PHPT.The sensivity for detection of abnormal parathyroid glands was 88.6% on ultrasonography (US), 76.9% on magnetic resonance imaging (MRI), 74.3% on Tl-Tc subtraction scintigraphy and 68.8% on computed tomography.We concluded that US should be performed first, with MRI as a supplementary method, for the detection of abnormal parathyroid glands and the evaluation of invasion within the body.
