(HealthDay News) -- Ultrasound imaging, also known as sonography, uses high-frequency sound waves to produce pictures of the inside of your body, says the University of California, San Francisco.
To prepare for an ultrasound, UCSF encourages patients to:
- Inform the provider if you have any allergies or need interpreting services.
- Leave valuables at home or in your hospital room.
- Listen to the doctor's preparation instructions. You may be asked to drink water before the test.
- Be ready for a 30- to 60-minute exam.
- Ask the technologist any questions you may have.
