Parathyroid gland radionuclide scanning--methods and indications.

摘要: The usefulness of preoperative radionuclide scanning the parathyroid glands in patients with primary or secondary hyperparathyroidism was long controversial because available techniques were limited diagnostic efficacy. Technetium-99m-labeled sestamibi (99Tc-sestamibi) is a new radiopharmaceutical agent easily detected by gamma cameras. first imaging studies done 99Tc-sestamibi about 10 years ago used double-phase technique to separate thyroid and tissue. Although promising, this method less than ideal, particularly multiple gland hyperparathyroidism. For several years, we have been using subtraction between two images acquired simultaneously, one 99Tc-sestamibi, which binds tissue, other 123-iodine, only remarkable efficacy both invites reappraisal place as localization procedure reduce need for repeat surgery. selecting candidates unilateral surgery among discussed.
