Doppler ultrasound
measuring blood flow in vessels via sound waves, umbilical cord
Doppler ultrasound is a diagnostic imaging technique that uses high-frequency sound waves to measure the velocity and direction of blood flow in the blood vessels and organs inside the human body.
During a Doppler ultrasound procedure, a special transducer is placed on the skin and emits sound waves that penetrate through the tissues and reflect back from the blood cells. The reflected waves are detected by the same transducer and processed by a computer to create an image of the blood flow. The velocity and direction of the blood flow are displayed as color-coded signals on a monitor.
Doppler ultrasound is commonly used to assess the blood flow in the arteries and veins of the arms, legs, neck, and abdomen. This procedure is non-invasive, painless, and does not involve radiation exposure, making it a safe and widely used diagnostic tool in modern medicine.
Doppler ultrasound can be used to detect and diagnose a variety of medical conditions, including blood clots, deep vein thrombosis, arterial stenosis, peripheral arterial disease, varicose veins, and many others. It is also used during pregnancy to monitor the blood flow in the fetus and placenta and assess the risk of complications.
