Ultrasound Imaging:
Updated July 23, 2009

What is Ultrasound imaging?

Ultrasound images are taken using a small, hand-held device, called a transducer. When the device is placed on the skin, it sends sound waves into your body.

These waves bounce off your internal organs and go back to the transducer to make a picture.

Ultrasounds can also be used to guide needles used in biopsy procedures for the breast, liver, thyroid, and prostate.

How should I get ready for an Ultrasound?

If you are having an abdomen, aorta, gallbladder, pancreas and biliary tract ultrasound, you can not eat, drink, smoke or chew gum after midnight the night before your exam.

For renal and pelvic ultrasound you must drink 1000 ml (32 oz) of clear liquids 45 minutes before your appointment. Do not empty your bladder because having a full bladder helps sound waves travel in your body.

For an obstetrical ultrasound, you must drink 750 ml (24 oz.) of clear liquids 45 minutes before your appointment time. Do not empty your bladder.

If you are in pain because your bladder is fuller than required. Empty out a cup of urine to make you feel better.

Other ultrasounds including biophysical ultrasound, breast, thyroid, scrotum, carotid arteries and veins do not require you to do any preparation.

For children under 10, please call the diagnostic department for more information.

Come to the diagnostic imaging department 20 minutes before your appointment.

What can I expect during an Ultrasound?

The Ultrasound technologist, a sonographer, may ask you to change into a hospital gown, depending on what area is being scanned.

You will be lying down throughout the exam. You may also have to move from side to side for the sonographer to get the best images.

The sonographer will apply clear gel to the area being examined.

In order to get good images, the sonographer must press the transducer against your skin.

You may have to hold your breath for short periods of time.

How long will the Ultrasound take?

25 minutes to 1 hour depending on the area being examined.


The technologists are unable to give test results. Your doctor will receive a copy of the report within approximately 1 week. If you have any questions, concerns or if you are unable to keep your appointment, please do not hesitate to call the booking office at 742-2571 or toll free 1-877-742-2571.
