In total 184 studies, which included thyroid uptake and scintigraphy, were performed in 68 hyperthyroid patients: 67% female and 33% male to investigate their thyroid conditions. The aim of the present study was to illustrate the role of uptake and scintigraphy tests in determining the thyroid status of hyperthyroid patients. The uptake study was performed by oral administration of 100 -200 μCi of 131 I as sodium-iodide and counting the radioactivity at 2 and 24 hrs, whereas thyroid

... was performed 20 minutes after an intravenous injection of 2 -4 mCi of 99m Tc-pertechnetate. The present results of thyroid uptake and scintigraphy successfully identified the thyroid condition in different states. The present results were also compared with some reported data and found to be fair in good agreement.
