What is a Thyroid Scan?
A thyroid scan shows how your thyroid gland is working using a radioactive tracer.
The tracer localises in the thyroid gland; the distribution is scanned (detected) using a Gamma Camera. The scan gives information on the size, shape, position and function of the gland.
What is this scan used for?
Thyroid scans can be used to:
- Check if your thyroid is working properly.
- Help diagnose problems with your thyroid gland, such as an overactive thyroid gland (hyperthyroidism), thyroid cancer or other growths.
- Assess the nature of a lump (nodule) discovered in your gland.
- Detect areas of abnormality, such as lumps or inflammation.
- Determine whether thyroid cancer has spread outside your thyroid gland.
- Look at how your thyroid gland may have changed following surgery, radiotherapy or chemotherapy.
