Many of us have had thyroid ultrasound scans. What most of us don't know is what the operator can see and how that is interpreted.
The paper below shows many of the variations that are seen and what they indicate.I thought it remarkable quite how distinctive some of them are. Most certainly it strikes me that ultrasound would probably be a very useful adjunct to Thyroid peroxidase and Thyroglobulin antibody tests if there is any suspicion of Hashimoto's - or any question over interpretation of the antibody tests.
