A Doppler ultrasound is conducted to check the blood flow in veins, monitoring the presence of blood clot in blood vessels through ultrasound sound waves.
It is different from regular ultrasound as the blood flow is not visible. The entire process is non-invasive and can evaluate the blood flow by analysing the change in its pitch.
How is it done?
In a Doppler Ultrasound, an expert technician trained in ultrasound imaging uses a small hand-held device called transducer against the skin in the area which is under observation. It is an excellent tool to detect the blood vessels using a dye in X-rays, a great substitute for angiography.
It is widely used to detect the following problems:
- Identifying clots in blood
- Monitoring the Functioning of valves in leg veins to save it from causing the pool of fluids in legs.
- Genetical heart disease and problem in valves
- A congested artery (arterial occlusion)
- Reduced blood circulation into your legs (peripheral artery disease)
- Protruding arteries (aneurysms)
- The contraction in an artery, such as in your neck (carotid artery stenosis)
