Abstract:
This study include 77 patients in different age, sex, center of origin and type of food and drink intake. To study the relationship between thyroid function test and thyroid uptake using 99mTc. The study was also designed to help in determination of the normal range of the thyroid uptake in Sudanese as well as the possibility of replacing the TFT test by thyroid uptake. The study was conducted at RICK; nuclear medicine department (gamma camera and RIA) for five months From MAY to AUG 2009. the level of thyroid hormones T4, T3 and TSH in the subject’s blood were measured using sensitive RIA method against the thyroid uptake value in the gamma camera (mediso).the result of this study showed that, there was a direct relationship between thyroid uptake and the level of the thyroid related hormones(for individual). The percentage of thyroid uptake for the subjects included in the study was ranging between 1.2 and 8.0. also the study indicated that There were possibilities of using thyroid uptake only as a diagnostic tool for thyroid activity without TFT due to the ability of thyroid uptake in giving sufficient information concerning thyroid status.
