Localization of parathyroid pathology prior to reoperative neck exploration for hyperparathyroidism decreases operating time and potential morbidity. A color-graded nuclear scan using computer subtraction of technetium 99m from thallium-201 images is an accurate means of locating the parathyroid tissue in patients who have previously had one or more neck explorations.
