How the Test is Performed
Ultrasound is a painless method that uses sound waves to create images of the inside of the body. The test is usually done in the ultrasound or radiology department. It also can be done in a clinic.
The test is done in this way:
- You lie down with your neck on a pillow or other soft support. Your neck is stretched slightly.
- The ultrasound technician applies a water-based gel on your neck to help with transmit the sound waves.
- Next, the technician moves a wand, called a transducer, back and forth over the area. The transducer gives off sound waves. The sound waves go through your body and bounce off the area being studied (in this case, the thyroid gland). A computer looks at the pattern that the sound waves create when bouncing back, and creates an image from them.
