Ultrasonography, Doppler - 새창 Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow. (Stedman, 25th ed)
Synonyms :
Ultrasonography, Doppler, Color - 새창 Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
Synonyms : Color Doppler Ultrasonography, Color Ultrasonography, Doppler, Doppler Color Ultrasonography, Ultrasonography, Doppler Color
Ultrasonography, Doppler, Duplex - 새창 Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.
Synonyms : Doppler Duplex Ultrasonography, Duplex Doppler Ultrasonography, Duplex Ultrasonography, Doppler, Ultrasonography, Doppler Duplex
Ultrasonography, Doppler, Pulsed - 새창 Ultrasonography applying the Doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return.
Synonyms : Doppler Pulsed Ultrasonography, Pulsed Doppler Ultrasonography, Pulsed Ultrasonography, Doppler, Ultrasonography, Doppler Pulsed
Ultrasonography, Doppler, Transcranial - 새창 A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.
