[Localization of primary hyperparathyroidism in US, CT, MRI and scintigraphy].
A value of preoperative localization tests for primary hyperparathyroidism is controversial. Many preoperative localization studies such as ultrasound, computed tomography scanning, magnetic resonance imaging (MRI) and radionuclide scanning have been proposed to facilitate unilateral neck exploration and to improve the surgical success rate. The accuracy of these investigations, however, has not approached that of an experienced parathyroid surgeon. All imaging techniques were not evaluated for small glands weighting less than 250 mg. But these tests showed high sensitivity and specificity for tumors weighting more than 1 g.
