Study of Thyroid Uptake of TC99m and Levels of Thyroid Hormones in Blood

Abstract

A radioactive Technetium pertechnetate (99mTcO4) uptake by thyroid gland is often performed to evaluate its functional status. This study is aim to see how accurate this uptake correlates with the Tri-iodothyronine (T3), Tetra-iodothyronine (T4) and thyroid stimulating hormone(TSH), radioimmunoassay (RIA) levels were studied in a total of 100 adult patients in the age ranged between 20 to 60 years, who were referred to the department of Nuclear Medicine in the Radiation and Isotopes-center of Khartoum (RICK) for thyroid radioactive Technetium pertechnetate uptake and Thyroid function Test (TFT), respectively. It was observed that there was a significant positive correlation between thyroid uptakes of (99mTcO4) values and T3( p< 0.01) & T4 ( p< 0.01) values , but a negative insignificant correlation was observed with values of TSH ( p> 0.01).
