Ultrasound is also indicated as part of a biopsy of the thyroid gland or surrounding tissues to check for cytologic abnormalities, if present.

3. What to prepare before thyroid ultrasound?

Before entering the ultrasound, you should remove the necklace and other accessories from the neck area. In addition, you are also asked to take off your shirt to expose your neck area and lie on your back when you enter the ultrasound room.
