Technetium-99m thyroid scan

A Technetium-99m thyroid scan is a diagnostic imaging test used to evaluate thyroid gland function and anatomy. During the procedure, a small amount of a radioactive substance called technetium-99m is injected into a vein. This radioactive material is absorbed by the thyroid, which helps imaging devices create detailed pictures of the gland. The scan can identify issues like nodules, tumors, or abnormal activity, aiding in diagnosing conditions such as hyperthyroidism or hypothyroidism. The amount of radioactivity used is very low, and the scan is quick, providing valuable information about the thyroid’s structure and function.
