Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing the body to high-frequency sound waves to produce images inside the body. Ultrasound exams do not use ionizing radiation (as used in X-rays). Because ultrasound images are captured in real time, can show the structure and movement of internal organs of the body, as well as blood flowing through blood vessels.

Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

Thyroid ultrasound produces a picture of the thyroid gland. The thyroid gland is located at the front of the neck, just below the Adam’s apple, and shaped like a butterfly with two lobes on either side of the neck connected by a narrow band of tissue is one of nine endocrine glands located in the body that produce and send hormones into the bloodstream.

Some common uses of the procedure

Usually, the thyroid ultrasound is used to help diagnose:

Doses of iodine are referred by physicians for patients with thyroid gland problems. The I-131 is a radioactive isotope, emitting both beta particles and gamma radiation, with an average life of 8.04 days. The basic principle that justifies their use in therapy is unique physiological property owned by the thyroid gland to concentrate this element. This will deliver locally and directed a high dose of radiation in the functioning thyroid tissue respecting the rest of the body.

Ablative dose of iodine Central Nuclear Medicine, Nuclear Medicine thyroid gland of Central America, Thyroid Patient Therapy with I-131 is used both in benign, as in hyperthyroidism (Graves’ disease and functioning nodules) and some cases of multinodular goiter non-toxic and well-differentiated cancer (papillary or follicular) thyroid, both locally and advanced.

The indication, dosing and timing of radiation treatment should be taken in conjunction with the endocrinologist and surgeon and specialist in nuclear medicine. The only contra-indication for treatment with I-131 is pregnancy. Therefore, this possibility should be ruled out forever in every woman of childbearing age.
