How is thyroid ultrasound used to diagnose a multinodular goiter?

Sonar images: Ultrasound uses the variation in the 2 dimensional images produced by scanning the thyroid like a fisherman uses sonar to find a school of fish under his boat. Enough thyroid us's have been done to develop pictures of how big each part of the gland should be at a given age in a given condition.

Ultrasound: Sonogram of the thyroid can detect focal areas of solid or cystic lesions. These are called hypoechoic and represent localized inflammation. Occasionally one of these nodules grows and may transform to a malignancy.
