Thyroid scintigraphy is a radionuclide diagnostic method that allows assessment of the structure and function of the thyroid gland and detection of pathological changes in its tissues. The examination is performed with the administration of a radiopharmaceutical agent that accumulates in the glandular tissue and is detected by a gamma camera.
When is thyroid scintigraphy required?
In cases of suspected hyperthyroidism or hypothyroidism, thyroid nodules, thyroiditis, and goiter. For the diagnosis of autonomous adenomas, multinodular goiter, and thyroid tumors. To identify hyperfunctioning (“hot”) and non-functioning (“cold”) nodules. During monitoring of thyroid status after treatment or surgery.
How is the examination performed?
A radiopharmaceutical agent is administered intravenously or orally (most commonly technetium-99m or iodine-131). After 20–30 minutes, scanning of the thyroid gland is performed using a gamma camera. The duration of the procedure is 30–60 minutes; special preparation may include temporary discontinuation of iodine-containing medications and thyroid hormone therapy.
Main advantages of thyroid scintigraphy in Belarus
High diagnostic accuracy for nodular lesions and functional disorders. The ability to determine the functional activity of nodules (“hot” and “cold” nodules). Painless procedure, minimal radiation exposure, and the possibility of early detection of pathologies.
Belarusian medical centers are equipped with modern gamma cameras that ensure accurate diagnosis of thyroid diseases. Experienced specialists perform the examination with high precision and patient safety.
