Why are the reasons for biopsy of cold spot thyroid scan results?
Thyroid cold spots are areas of decreased radionuclidic uptake, meaning that particular area of the thyroid is not metabolizing iodine. These finding are consistent with cysts, hypothyroidism, benign growths, inflammation, or malignancy. In addition to a scan, an uptake is often performed. This is done by counting the activity of the radioactive iodine (RAI) with a gamma probe, administering the RAI (commonly in pill form), and then positioning the patient about 8cm from the probe and counting activity over the thyroid commonly at 6 and 24 hours post RAI administration. This is helpful in determining if the thyroid is hypo, hyper, or normal (euthyroid). Uptake percentages relative to the initial activity are considered normal within the ranges of 10-30% respectively. Thyroid inflammtion can mimic the uptake values of hypothyroidism. In addition, the patient should not have any study using RAI if they have a study requiring the use of Iodine contrast (eg contrast enhanced CT), take multivitamins containing iodine, have recently taken cold medicine containing iodine or antihistimines including diet pills, or if they are on a special diet containing kelp or seeweed tablets. In patients with known hypothyroidism, thyroid suppressive medication (eg Synthyroid) should be discontinued for 2-6wks prior to RAI administration. Back to the scan... A single cold spot is malignant in about 10-20% of cases. Therefore, a biopsy is helpful for providing a differential diagnosis using laboratory histology.

How common is thyroid disease?
The thyroid gland is located on the front part of the neck below the thyroid cartilage (Adam's apple). The gland produces thyroid hormones, which regulate body metabolism. Thyroid hormones are important in regulating body energy, the body's use of other hormones and vitamins, and the growth and maturation of body tissues. Diseases of the thyroid gland can result in either production of too much thyroid hormone, thyroid nodules, and/or goiter. All types of thyroid problems in women are much more common than thyroid problems in men.
What is the Difference between hot and cold thyroid nodule?
The difference between hot and cold thyroid nodules refers to the appearance of the thyroid when viewed by a Nuclear Medicine Thyroid Scan. During a thyroid scan, the patient is given radioactive iodine which is taken orally. The radioactive iodine is absorbed into the bloodstream and gets picked up by functioning thyroid tissue. The thyroid utilizes iodine in its function of producing thyroid hormones. With a Nuclear Medicine scan, the radioactive iodine acts like non-radioactive iodine and is absorbed by the thyroid gland to be used in the production of thyroid hormones. Therefore, functioning thyroid tissue will become radioactive by the absorption of the radioactive iodine. Areas of the thyroid which are overly functioning will pick up more radioactive iodine than normal tissue and are referred to as being "hot". Areas of the thyroid that are functioning less than normal or not at all will pick up less or none of the radioactive iodine. These areas are referred to as being "cold". With the use of special "cameras" the radioactive iodine is detected in the thyroid gland and a picture is formed. The "hot" areas will show up darker than normal tissue and the "cold" areas will show up as lighter than normal tissue or as completely blank areas. The "hot" nodules are overly functioning thyroid tissue, very often palpable from the outer surface of the skin, and are sometimes cancerous tissue. The "cold" nodules are also sometimes palpable from the outer skin surface. These non-functioning areas can be scar tissue, cysts or a variety of non thyroid tissue infiltrating the thyroid gland.
