Doppler ultrasound may be used to check blood flow to an area. It may also be needed to check for injuries to blood vessels or assess treatment. Common reasons for use include: Look for cause of blood pooling in legs such as valve problems in your leg veins; Heart valve defects and congenital heart disease Blockage in artery ; Peripheral artery

Doppler ultrasound

Venous Doppler ultrasound is an imaging test of the veins in the arms and legs to determine if you have blood clots in your extremities. A Doppler ultrasound is a test that uses high-frequency sound waves to measure the amount of blood flow through your arteries and veins, usually those that supply blood to your arms and legs.

It can also be used to provide information regarding the perfusion of blood flow in an organ or within an area of interest. Doppler ultrasound in general and obstetric ultrasound scanners uses pulsed wave ultrasound. This allows measurement of the depth (or range) of the flow site. Additionally, the size of the sample volume (or range gate) can be changed. Pulsed wave ultrasound is used to provide data for Doppler sonograms and color flow images. Color flow Doppler (ultrasound) Dr Mohammad Osama Hussein Yonso◉and Dr David Carroll◉et al. The use of color flow Doppler (CFD) or color Doppler imaging (CDI) (or simply color Doppler) sonography allows the visualization of flow direction and velocity within a user defined area.
