What is the normal echogenicity of the thyroid?

What is the normal echogenicity of the thyroid?

The normal thyroid tissue is homogeneously hyperechoic and brighter than the surrounding muscles.

Does echogenic foci mean cancer?

Conclusion: All categories of echogenic foci except those with large comet-tail artifacts are associated with high cancer risk. Identification of large comet-tail artifacts suggests benignity. Nodules with small comet-tail artifacts have a high incidence of malignancy in hypoechoic nodules.

What is echogenic foci in thyroid nodule?

Echogenic foci are commonly identified on thyroid ultrasound. Some echogenic foci such as microcalcifications are associated with increased risk for malignancy, while others such as comet tail artifact are associated with low risk. Microcalcifications are tiny and without posterior shadowing.

What is the difference between a thyroid nodule and a goiter?

An enlarged thyroid gland can be felt as a lump under the skin at the front of the neck. When it is large enough to see easily, it’s called a goiter. A thyroid nodule is a lump or enlarged area in the thyroid gland.

What is Isoechoic?

Isoechoic – Tissue or structures which produces an echo of the same strength as that of the surrounding structures or tissues, making it difficult to isolate.

Will echogenic focus go away?

The echogenic focus may go away on its own or it may not, but it doesn’t affect a child’s cardiac function so there is no need for treatment or even follow-up testing to see if it is still there.

What percentage of calcified thyroid nodules are cancerous?

Calcifications on thyroid ultrasound do not necessarily represent thyroid cancer. Thyroid nodules are a very common that can be detected in up to 2/3rds of people, often on a physical examination or a test done for other reasons. While most thyroid nodules are not cancer (benign), ~5% are cancerous.
