Radionuclide method for functional and structural examination of the thyroid gland

Full text: The aim of this study is development and routine daily practice of the radionuclide method for tracking of the thyroid gland functional status and structure. 168 patients with various thyroid diseases were examined. Nuclear medicine examination is held by gamma camera (Siemens and ADAK). 74 MBq 99m Tc-pertechnetate is injected intravenous. The activity of full and empty syringe is measured. Static scintigrams of full and empty syringes and injection place and duration 10 seconds are carried out. On 20 th minute a static scintigraphy of the thyroid gland with a duration of 300 seconds in front position is held. The individual dose calibration factor is calculated. The functional status of thyroid gland as well as its structural changes is determined. In addition, the relationships between the accumulation of radiopharmaceutical in the salivary glands and thyroid are determined. 168 patients are studied, 97 of them are with euthyroidism, 71 with hyperthyroidism and 19 - with hypothyroidism. The nuclear medicine diagnostic method provides information about functional and structural condition of the thyroid gland. The study is determining for decision to conduct the metabolic brachytherapy of hyperthyroid conditions
