Thyroid Scans

A thyroid scan is a medical imaging test that evaluates the function and structure of the thyroid gland, which regulates metabolism. During the scan, a small amount of radioactive material is ingested or injected, and a special camera detects the radiation emitted. This creates images showing how the thyroid absorbs iodine, highlighting areas of normal or abnormal activity. The scan helps diagnose conditions like hyperthyroidism, hypothyroidism, nodules, or cancer. It’s a safe procedure with minimal radiation exposure, providing valuable information for diagnosis and treatment planning.
