An ultrasound involves using high-frequency sound waves to produce pictures
of inside the body. These high-frequency sound waves are inaudible to
the human ear and are transmitted through the body using an instrument
called a transducer. As these sound waves bounce off internal organs,
fluids and tissues the transducer records tiny changes in the sounds pitch
and direction. These waves are measured and displayed using a computer,
and used to create an image on the monitor.
Why an Ultrasound?
An ultrasound creates images of soft tissue structures including:
- Thyroid gland
- Female reproductive organs
- Babies inside the uterus
Ultrasounds can also be used to measure:
- The flow of blood in the arteries and veins and detect blockages
- Cysts or abnormal growths in the liver, spleen or pancreas
- Abnormal enlargement of the spleen
- Cancer of the liver
- Heart conditions and damage after a heart attack
How to Prepare for Your Ultrasound
Ultrasounds are fairly simple, non-invasive tests that usually require
no special preparation. You should wear comfortable, loose-fitting clothing
for your exam, and you may be required to remove all of your clothing
and jewelry in the area being scanned. You may also be asked to wear a
gown during the procedure.
Any required preparation will depend on the type of examination you’ll
have, with many requiring no preparation at all. For some tests, however,
your physician my instruct you not to eat or drink for 12 hours before
your procedure, while for other tests you may be instructed to drink up
to 6 glasses of water two hours prior to your exam and avoid urination
so your bladder is full. If preparation is required, please follow your
physician’s instructions carefully so we can obtain an accurate reading.
Your physician will give you a complete set of instructions before your
ultrasound so you can be fully prepared for it. If you have any questions
as to what you need to do, or how the procedure is performed, you should
ask your doctor.
During Your Ultrasound
During your ultrasound you will most likely be asked to lay face-up on
an examination table that is padded and can be titled or moved. A registered
diagnostic medical sonographer will perform the exam. He or she will begin
by applying a small amount of a clear, water-based gel to the area of
your body being studied. This gel is not harmful to your skin and can
be wiped off as soon as the test is complete. The radiology technician
will then take the transducer to your skin, pressing it down slightly
in various locations. You may be asked to hold your breath for brief periods of time.
The ultrasound will only last several minutes, after which the radiologist
will read the exam and study the images. The radiologist will send the
results to your physician who will discuss them with you. This is a painless
procedure and there are no known risks to having an ultrasound done.
