The uptake of Tc-99m tetrofosmin (TF) is reported in a case of parathyroid adenoma. A 65-year-old woman was studied on different days with TF, Tc-99m sestamibi (MIBI) and Tl-201 chloride (TI). TF and MIBI injections were preceded by oral administration of potassium perchlorate. Clear identification of the adenoma was observed in all scans. No further information was obtained using a subtraction technique with Tc-99m pertechnetate. Regarding the thyroid/parathyroid ratio, different kinetics between TF and MIBI appear to be demonstrated. In particular, thyroid washout was observed with MIBI but not with TI.
