Thyroid Ultrasound

Your doctor has requested a thyroid ultrasound. The most common indication for an ultrasound of your neck is a palpable neck mass. When a mass is found in the neck, the origin may not be obvious from a clinical examination; therefore, an ultrasound study is necessary to determine the origin and make-up (solid or water-filled mass) of the neck mass. At DVT Diagnostic Services, INC., we have a specialized team of Radiologists and technologists who are experts in ultrasound radiology.

During Your Exam


Upon arrival, the diagnostic medical sonographer will explain your procedure and answer any questions you may have.

You will be asked to lie on the examination table with a pillow or bolster under your shoulders and your head extended back.

A warm gel will be applied to your neck (the gel is very similar to hair styling gel). The gel helps the sound waves to get from the machine to your body more easily.

A transducer, a small microphone-like device, is placed over your neck. There is no pain involved; however, you may feel mild pressure from the transducer.

Sound waves pass harmlessly through the skin from the transducer.

A television monitor shows images of your neck as the probe converts the echoes to electrical signals. These moving images can be viewed immediately, recorded, and/or photographed for physician review. Occasionally, additional images may be needed following review by an imaging physician.

Your procedure will take approximately 30 to 45 minutes.

After Your Exam


There are no post-examination instructions.Your study will be reviewed by a board certified radiologist and the results will be sent to your physician. Your physician will discuss these results with you and explain what they mean in relation to your health.
