There are several different types of thyroid ultrasound images, 

each can provide valuable information about the health of your thyroid gland. 

A thyroid ultrasound images can help identify benign or malignant nodules, as well as assess the size and function of your thyroid gland.  

thyroid ultrasound images are usually quick and painless, and can be done on an outpatient basis. 

1. Normal thyroid ultrasound images usually show a well-defined gland with smooth borders and no evidence of nodules 

2. In some cases, small areas of calcification may be seen within the gland, but this finding is not considered abnormal. 

The presence of a dominant follicle is also considered normal and should not be a cause for concern. 

3. If no lumps or other abnormalities are identified on thyroid ultrasound, further investigation with additional 

imaging (eg, CT scan) or biopsy may rule out thyroid cancer or other malignancy.
