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.
