Thyroid scan procedure
You’ll lie down on an examination table for a thyroid scan without RAIU. The technologist will tip your head back so that your neck is extended. They’ll then use a scanner or camera to take photos of your thyroid, usually from at least three different angles. You’ll be asked to stay very still while the images are taken. The process takes about 30 minutes.

Abnormal results indicate hypo or hyperthyroidism, inflammations, or other health conditions like Hashimoto’s disease, Grave’s disease, etc.
