Tests after a thyroid cancer diagnosis

You may have more tests after your diagnosis to find out:

• How large is the cancer?
• Where exactly is the cancer?
• Has the cancer spread to any other parts of your body?

This is called staging. Staging tests for thyroid cancer include:

• MRI scan: A scan that uses magnetic energy to build up a picture of the tissues inside your body. During the scan you will lie inside a tunnel-like machine.
• CT scan: A type of X-ray that gives a detailed picture of the tissues inside your body.
• PET scan: A radioactive injection that will show up any cancer spread to other parts of your body on a CT scan picture.
