WHAT IS ULTRASOUND?

Ultrasound (or "sonography") is a procedure that uses high-frequency sound waves to show what is inside your body.

HOW DOES ULTRASOUND WORK?

Because the body contains over 90% water, sound waves can be used in some parts of the body just as sonar is used in the ocean. Each time the sound hits a tissue interface, like a blood vessel, an echo is sent back. Sophisticated, high-speed computers can use these echoes to create a picture of your internal organs. This results in a very detailed examination which aids the physician in his or her diagnosis.

In addition, at VIERA DIAGNOSTIC CENTER, some information is displayed using color-Doppler images and includes accurate blood flow measurements. This is called color-flow Doppler.

An ultrasound examination is fast, with very little discomfort. No radiation or x-rays are necessary.

WHAT YOU CAN EXPECT DURING YOUR ULTRASOUND EXAM?

You will be asked to lie down on a padded table and a gel will be spread on your skin above the area which is being examined. The technologist will move a device called a "transducer" slowly over your skin which has the gel on it, and an image will appear on a video screen. Pictures of this image will be made for permanent reference. You may be asked to hold your breath or assume different positions on the table. It is important that you remain as still as possible. Depending on the exam that was ordered, you may be a bit uncomfortable from the fullness of your bladder. For some pelvic examinations it is necessary to put a special type of transducer into the vagina.

WHAT WOULD AN ULTRASOUND TEST BE USED FOR?

Ultrasound is an excellent tool in several diagnostic situations, including: examining the fetus during pregnancy, visualizing certain gynecological functions in non-pregnant women, revealing information about tumors and cysts, evaluating the gallbladder and related organs, and for noninvasive evaluation of vascular disease.

HOW DO I PREPARE FOR THE TEST?

There are no general set instructions for all ultrasound examinations. Your physician will give you instructions on how to prepare for your specific exam. It is important to follow these instructions to ensure the most accurate diagnostic results.

In addition, please advise the staff if you have had previous ultrasound exams so that our physician can use them for comparison.

HOW LONG WILL THE EXAM TAKE?

The length of the exam varies with the type of ultrasound exam you are having. Please check with us for the estimated time required in your case.
