Joðskanninn

Joðskanninn is a medical device used for diagnostic imaging. It utilizes a small amount of radioactive iodine, or a related radioisotope, to assess the function of the thyroid gland. The device measures the uptake of this radioactive substance by the thyroid cells. This information helps physicians to diagnose a variety of thyroid conditions, including hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid). It can also be used to detect thyroid nodules or assess the effectiveness of thyroid cancer treatment.

The procedure involves administering the radioactive iodine, usually orally in capsule form or as a liquid. After a specific period, typically several hours or a day, the patient is positioned in front of the joðskanninn. The device emits gamma rays from the thyroid, which are detected and recorded. A computer then processes this data to create an image or a graph representing the thyroid's activity. The amount of radiation used is very small, and the procedure is generally considered safe. It is a non-invasive test that provides valuable insights into thyroid health.
