Thyroid Ultrasound Imaging
If your doctor indicates that your thyroid function is abnormal, a thyroid ultrasound may be ordered, especially if he feels a lump or growth on your neck. An ultrasound takes images of that lump, giving your doctor more information about potential treatment. It also checks for underactive or overactive thyroid gland.
Here are some symptoms that could prompt a thyroid ultrasound:
- Graves Disease
Thyroid ultrasound uses sound waves to produce pictures of the thyroid gland in the neck
A thyroid ultrasound is an imaging method to see the thyroid, a gland in the neck that regulates metabolism (the many processes that control the rate of activity in cells and tissues).
Ultrasound is a painless method that uses sound waves to create images of the inside of the body. The test is often done in ultrasound and no radiation is used with this method of imaging.
What are some common uses of the procedure?
The definite cause of the thyroid nodules is not known but various factors which might be responsible for the formation are deficiency of iodine, overgrowth of normal thyroid tissue, and fluid-filled cavities or cysts in the thyroid. Usually, it does not cause any symptoms and is hard to diagnose.
But in a few cases, the patient might feel a lump or may have difficulty in swallowing or breathing. Treatment for thyroid nodules is done on the basis of causing factors and severity of the disease.
How does the Thyroid Ultrasound procedure work?
A small amount of gel is applied to the front part of the neck where the thyroid is located to perform an ultrasound of the thyroid. The sonographer then scans over the thyroid with a transducer and images are obtained.
The transducer sends high-frequency sound waves through your body. The waves echo as they hit a dense object, such as an organ or bone. Those echoes are then reflected back into a computer. The sound waves are at too high of a pitch for the human ear to hear. They form a picture that can be interpreted by the doctor. This is a painless, non-invasive procedure.
