Thyroid nuclear scan
This scan involves taking orally a small dose of radioactive iodine. The iodine is taken up by the thyroid and produces an image. "cold" areas are places with no iodine uptake. "hot" areas have a lot of uptake. The radiologist also calculates the percent uptake of the iodine. This test is important in the diagnosis of hyperthyoidism, thyroid cancer, and follow up of thyroid cancer.
