The tests are also used for research in cognitive neuroscience. Vascular ultrasonography helps determine multiple factors within the circulatory system. It can evaluate central abdominal and peripheral arteries and veins ; it helps determine the amount of vascular stenosis narrowing or occlusion complete blockage within an artery; it assists in ruling out aneurysmal disease ; and it is the main aid to rule out thrombotic events. Duplex is an inexpensive, non-invasive way to determine pathology. It is used in for example:. Duplex evaluation is usually done prior to any invasive testing or surgical procedure.

The location and severity of arterial narrowings and occlusions can be identified.

The vascular sonographer can map disease in lower-extremity segments with great accuracy, though duplex scanning is more time-consuming than other lower-extremity arterial studies. An alternative to Doppler to visualize vessels is B-flow , [7] which digitally highlights weak flow reflectors mainly red blood cells while suppressing the signals from the surrounding stationary tissue.

It can visualize flowing blood and surrounding stationary tissues simultaneously.

Duplex Ultrasound

Doppler ultrasonography is widely used in renal ultrasonography. Renal vessels are easily depicted by the color Doppler technique in order to evaluate perfusion. Applying spectral Doppler to the renal artery and selected interlobular arteries, peak systolic velocities, resistive index and acceleration curves can be estimated Figure 4 , e. Doppler echocardiography is the use of Doppler ultrasonography to examine the heart. One of the limitations is that the ultrasound beam should be as parallel to the blood flow as possible.

Contrast-enhanced ultrasound using gas-filled microbubble contrast media can be used to improve velocity or other flow-related medical measurements. Doppler fetal monitors , although usually not technically -graphy but rather sound-generating, use the Doppler effect to detect the fetal heartbeat for prenatal care. These are hand-held, and some models also display the heart rate in beats per minute BPM. Use of this monitor is sometimes known as Doppler auscultation.

The Doppler fetal monitor is commonly referred to simply as a Doppler or fetal Doppler.
