With the images obtained through thyroid scintigraphy, it’s possible to determine the size of the gland and its location in the neck, and to identify areas of abnormality. This examination is useful to characterize the function of a node discovered by your physician or visualized through ultrasonography.

If a malfunction of the metabolism of the thyroid gland occurs, it will affect the level of thyroid hormones in the blood, causing hyper or hypothyroidism. In these cases, VM-Med physicians can evaluate the rate of iodine uptake in the thyroid gland by having the patient drink a small quantity of slightly radioactive iodine (iodine-123). The scintigraphic imagery is produced within a few hours, allowing for the completion of the examination in one day.


  • Information will be provided when appointment is made by telephone.

Approximate duration:

  • One hour for the standard procedure or five hours if the examination is performed with iodine-123 but you can leave the clinic between the administration of iodine and the moment when the photos are produced.
