What Is Doppler Sonography?
Doppler sonography, or Doppler ultrasound, is a medical imaging technique that uses ultrasound enhanced by the Doppler effect. The Doppler effect generally uses a change in the pitch of sound waves that are measured by an ultrasound-receiving device such as a transducer. Colored Doppler images often provide helpful information about the flow and movement of blood and inner areas of the body. This technique is commonly used during pregnancy to provide detailed images of a developing unborn baby. Other uses for Doppler sonography may include visual examinations of tendons, joints and muscles as well as internal organs.
