title: Parathyroid lesions localized by radionuclide subtraction and ultrasound.
abstract: Radionuclide subtraction technique and gray-scale echography were used to localize parathyroid lesions in 6 patients with primary hyperparathyroidism. In 3 cases, surgery verified the scintigraphic findings. All lesions weighed less than 1 g, with the smallest weighing 350 mg. These procedures provide complementary information in preoperative localization of hyperfunctioning parathyroid tissue.
