Speed and Direction of Blood flow – Doppler Ultrasound

Doppler ultrasound is usually utilized in the clinical adjusting to evaluate and estimate blood flow in both the major (large) and the minor (tiny) vessels of the body. The normal and abnormal sign waveforms can be shown by the spectral Doppler technique. The sign waveform is individual to each vessel. Thus, it is significant for the operator and the clinicians to understand the normal and abnormal diagnostic in a spectral Doppler show. 

What are the advantages of using Doppler ultrasound? 

Doppler ultrasound helps in many conditions’ diagnosis such as Blood clots, Poorly functioning valves in leg veins, which can cause blood or other fluids to pool in the legs (venous insufficiency), Heart valve defects and congenital heart disease, A blocked artery (arterial occlusion), Decreased blood circulation into legs (peripheral artery disease), Bulging arteries (aneurysms), and Narrowing of an artery, such as in the neck (carotid artery stenosis), etc…

SONOSIF ‘s Research and Development team usually recommends the Wireless 3 in 1 Ultrasound Scanner Triple headed: convex, Linear, and cardiac probe 3in1-CLC2CD  to our cardiologists, cardiovascular surgeons, and hematologists clients.

In Doppler imaging of the blood, the constant object usually is the probe, and the shifting reflectors that produce the returning signal echoes are originally the red cells. The Doppler shift frequency or the Doppler-shift is known as the variation between the frequencies of transmitted and received of ultrasound waves echoes.

Doppler ultrasound test uses reflected sound waves to see how blood flows through a blood vessel. It helps doctors assess the blood flow through major arteries and veins, such as those of the arms, legs, and neck. 

When there is a change in the rate of blood flow then the scanner shows possible interruptions or abnormalities that are associated with blockages, tumors, and other conditions. Doppler ultrasound scanners are the only devices that are effective to evaluate the blood flow to this extent that helps to determine the health and condition of the organ.

 The reason for which these scanners have become quite significant in the medical field is that they can be used to understand the severe cardiovascular conditions. 

Doppler Ultrasounds show a clear indication of blood pooling and changes in flow rate, which makes diagnosis much easier for the doctors. The abnormalities observed are seen in real-time using Color Doppler ultrasound scanners.
