Abstract

The thyroid gland is a small endocrine gland that is very important for most vital body functions. The thyroid gland is the main organ capable of taking iodine from the environment and using it for hormone synthesis. Two major thyroid hormones that are secreted are T3 (triiodothyronine) and T4 (thyroxine). If any thyroid problems are suspected, a doctor should be consulted. The diagnosis of thyroid changes is mainly based on hormone tests in the blood and ultrasound (UG). The UG test allows accurate assessment of thyroid changes, making this test a popular and useful tool for assessing and controlling thyroid disorders. Ultrasound is the most sensitive imaging technique for thyroid. It is important to mention that ultrasound test is non-invasive, widely available, inexpensive, and free of any ionizing radiation. The purpose of this article is to discuss the possibilities of thyroid examination during ultrasound examination.
