A Doppler ultrasound is a harmless test that can be utilized to gauge your blood course through veins by ricocheting high-recurrence sound waves (ultrasound) off flowing red platelets. An ordinary ultrasound utilizes sound waves to create pictures, yet can't show blood stream.
Power Doppler sonography is another strategy that shows the strength of the Doppler signal in shading, rather than the speed and heading data. It has multiple times the responsiveness of regular shading Doppler for identification of stream and is especially valuable for little vessels and those with low-speed stream.
