Ultrasound
What is an ultrasound?
Ultrasound examinations can be performed on most parts of the body and provide
excellent information about a variety of conditions - from pregnancy to gall
stones, varicose veins and even muscle tears.
During an ultrasound examination, sound waves are bounced back from parts of
the body (like sonar) to give black and white (or in some cases now, colour)
images.
Ultrasound is particularly useful in pregnancy as there are no known harmful
effects from its diagnostic use. Modern ultrasound equipment shows detail in
"real-time", not as still images. This enables a moving image to be seen on the
screen.
These examinations are carried out and interpreted by a radiologist (a doctor
trained in reading x-rays and ultrasounds) and a sonographer (a technologist
trained in ultrasound imaging).
The sonographer uses a transducer (a hand-held device which produces and
receives the sound waves) to display the images. The ultrasound procedure is
usually painless.
Your doctor will explain why an ultrasound examination is necessary and the
best choice of imaging for you. Your doctor may feel it is necessary for you to
have an x-ray or other procedure, as well as an ultrasound.
Preparation
You will need to make an appointment for this examination.
Depending on the ultrasound examination that your doctor has requested, you may
be asked to fast from food and fluids. Some examinations require you to drink a
significant amount of water prior to arriving so that your bladder is full. You
will be advised of the appropriate preparation when you make your appointment.
