Small thyroid on ultrasound
How accurate are thyroid ultrasounds?
Ultrasound is very sensitive and shows many nodules that cannot be felt. In some age groups, nodules are seen on ultrasound in as many as 70 percent of adults. The vast majority of these are benign regions of thyroid tissue that pose no health risk.
What the thyroid ultrasound will show you?
An ultrasound of the thyroid produces a picture of the thyroid gland and can help doctors diagnose: A nodule (lump) in the thyroid A thyroid gland that is not functioning properly Thyroid cancer
How is thyroid ultrasound used to diagnose a disease?
What imaging tests do doctors use to diagnose and find the cause of thyroid disease? Ultrasound. Ultrasound of the thyroid is most often used to look for, or more closely at, thyroid nodules. ... Thyroid scan. Health care professionals use a thyroid scan to look at the size, shape, and position of the thyroid gland. Radioactive iodine uptake test. ...
What does a thyroid look like in ultrasound?
Ultrasound Characteristics That Suggest a Benign Nodule. Sharp edges are seen all around the nodule. Nodule filled with fluid and not live tissue (a cyst) Lots of nodules throughout the thyroid (almost always a benign multi-nodular goiter)

Remaining Thyroid Tissue The remaining thyroid tissue rarely causes a diagnostic problem if we have information regarding the type of surgery performed on a patient. Remaining thyroid tissue appears as the normal thyroid parenchyma did be-fore any additional treatment or if there was no underlying parenchymal disease such as thyroiditis [13].

Imaging Technique For thyroid sonography, all patients were ex-amined in the supine position with the neck hyper - extended by placement of a folded towel beneath the scapula (Fig. 1).

Ultrasound can also be used to accurately guide a needle directly into a nodule when your doctor thinks a fine needle biopsy is needed. Once the initial evaluation is completed, thyroid ultrasound

THE THYROID. The thyroid is a small (25 grams) butterfly-shaped gland located at the base of the throat. The largest of the endocrine glands, it consists of two lobes joined by the isthmus. The thyroid hugs the trachea on either side at the second and third tracheal ring, opposite of the 5th, 6th and 7th cervical vertebrae.

Although MTC constitutes a small fraction of thyroid malignancies, and an even smaller proportion of thyroid nodules, several reports suggest that routine screening of nodular goiters by CT assay is an appropriate approach (34-37). Such screening offers the possibility of finding tumors before they have metastasized, and MTC is rarely found on FNA.

Ultrasound, also known as sonography, uses a small transducer (probe) and ultrasound gel to create high-frequency sound waves.
