How should I prepare for my exam?

If your previous imaging was not done at one of our locations, you may be asked to contact your former provider and request that your film be sent to us for a comparison study.

  • You should follow an iodine-restricted diet for 10 days before your first appointment. Iodine can limit how much tracer is absorbed by your thyroid gland, which can make the exam less accurate.
