Why an Ultrasound?
Ultrasound is a useful way of examining many of the body's internal organs. You may need to undergo an ultrasound for a variety of reasons, such as:
- Assess a fetus
- Diagnose gallbladder disease
- Evaluate flow in blood vessels
- Evaluate a breast lump
- Check your thyroid gland
- Study your heart
- Diagnose some forms of infection
- Diagnose some forms of cancer
- Reveal abnormalities in the genitalia and prostate
- Evaluate abnormalities of the muscles and tendons
How should I get ready for the exam?
Your preparation will vary depending on the type of ultrasound exam you are having:

BIOPHYSICAL PROFILE OR PREGNANCY 28 WEEKS AND OVER - This exam requires a partially full bladder. Please drink 500ml (16 oz) of water 45 minutes prior to your appointment time.

What can I expect during the exam?
Based on the same principles as sonar, a technology used to detect underwater objects, the transducer generates and receives high-frequency sound waves that can't be heard by the human ear.
As the sonographer places the transducer on your skin, crystals inside the transducer emit pulses of sound waves that travel into your body. Your tissues, bones and body fluids reflect the sound waves and bounce them back to the transducer. The transducer then sends this information to a computer, which composes detailed images based on the patterns created by the sound waves.
Ultrasound is usually a painless procedure. However, you may experience some mild discomfort as the sonographer guides the transducer over your body, especially if you're required to have a full bladder. A typical ultrasound exam takes from 30 minutes to an hour.
