📖About Thyroid Scan
A thyroid scan is a nuclear medicine imaging test that uses a small dose of radioactive iodine or technetium tracer to visualise the size, shape, and functional activity of the thyroid gland. It helps distinguish between overactive nodules (hot nodules) and inactive ones (cold nodules), which carry different risks of malignancy. The scan is commonly ordered alongside thyroid function blood tests and ultrasound to build a complete picture of thyroid disease. It is a safe, low-radiation outpatient procedure performed in a nuclear medicine department.
