You will lie on your back on a high table with your neck
stretched out and a pillow under your shoulders. Gel will be spread on your
neck to improve the passage of the sound waves (they do not pass easily through
air). Sometimes a small water-filled bag or gelatin sponge is placed over your
throat to help conduct the sound waves. The transducer will be pressed against
your neck (or against the water-filled bag or gelatin sponge, if used), then
moved back and forth over your neck. A picture of your thyroid gland and the
tissue around it can be seen on a video monitor. You may be asked to turn your
head away from the side being scanned so the jawbone is out of the way.
The test takes about 30 minutes. You may be asked to wait until the
radiologist has reviewed the information. The radiologist may want to do
additional ultrasound views of your neck.

The gel may feel cold when it is applied
to your neck. Keeping your neck extended during the test may be uncomfortable,
