An ultrasound of the thyroid is typically used: to determine if a lump in the neck is arising from the thyroid or an adjacent structure. to analyze the appearance of thyroid nodules and determine if they are the more common benign nodule or if the nodule has features that require a biopsy.
Why would a doctor order a thyroid ultrasound?
A thyroid ultrasound may be ordered if a thyroid function test is abnormal or if you doctor feels a growth on your thyroid while examining your neck. An ultrasound can also check an underactive or overactive thyroid gland. You may receive a thyroid ultrasound as part of an overall physical exam.

Can a thyroid ultrasound detect hypothyroidism?
Thyroid ultrasound is crucial in the differential diagnosis of hypothyroidism, particularly, if thyroid antibodies are negative. It allows us to determine whether the thyroid is present and to visualise the parenchyma.
What does red mean on a thyroid ultrasound?
The mean velocity is then converted into a specific color. By definition, flow towards the transducer is depicted in red while flow away from the transducer is shown in blue. Different shades of red and blue are used to display velocity. Lighter shades of color are assigned to higher velocities.
What makes a thyroid nodule suspicious?
For the U.S. population, the lifetime risk of developing thyroid cancer is 1.1 percent. When a thyroid nodule is suspicious – meaning that it has characteristics that suggest thyroid cancer – the next step is usually a fine needle aspiration biopsy (FNAB).
How does thyroid cancer make you feel?

What size thyroid nodule is worrisome?
The nodules in 5% of each size group were classified as malignant. Six percent of the nodules 1 to 1.9 cm were considered suspicious, as were 8 to 9% of nodules in the larger size groups. Based on surgical pathology, 927 of 7348 nodules (13%) were cancers.

When looking at the lymph nodes in the neck with ultrasound, the following are important criteria which may lead to a FNA needle biopsy to confirm disease.
What does enlarged thyroid indicate?
A goiter is an enlarged thyroid gland that causes the neck to swell. A goiter is one of the most common thyroid disorders. It does not necessarily mean that the thyroid is functioning incorrectly. In some cases, however, it can signal an underlying thyroid disease that needs treatment.
