Abnormal tissues such as cystic nodules, adenomas and cancerous tumors appear as heterogeneous structures in thyroid ultrasound imagery. As explained by the National Center for Biotechnology Information, ultrasound technology is widely used in recognizing heterogeneous structural appearances and evaluating thyroid disorders. Heterogeneous ultrasound patterns provide physical imaging that may correlate to underactive or overactive thyroid conditions, helping to guide diagnosis and intervention. Thyroid ultrasound is used in conjunction with other diagnostic tools such as blood tests, thyroid scans and biopsies to reach a conclusive diagnosis for thyroid abnormalities.
Hypothyroidism refers to a low production of thyroid hormone and is often a result of thyroid damage caused by an autoimmune disease, explains WebMD.
