title: Parathyroid adenoma demonstrated with TI-201 SPECT.
abstract: A case of parathyroid adenoma with suppressed Tc-99m pertechnetate uptake of the thyroid due to L-thyroxine replacement therapy for hypothyroidism is reported. This case demonstrates successful localization of a parathyroid adenoma in the retrothyroid space using TI-201 SPECT. When the thyroid uptake of Tc-99m pertechnetate is reduced for whatever reason, a planar TI-201 followed by SPECT may be more helpful than TI-201/Tc-99m subtraction scintigraphy.
