Doppler ultrasound is a non-invasive procedure that uses ultrasound technology to assess blood flow in blood vessels. This test can detect blood clots, evaluate the function of veins, arteries, and heart valves, and check for conditions like congenital heart disease, aneurysms, or narrowing of arteries, such as those in the neck.
During the test, an ultrasound device, called a transducer, is used to capture images by sending sound waves through the skin. The transducer is pressed against the skin and moved across different areas, generating real-time images of blood flow. These images are then analyzed to diagnose and guide treatment if needed.
Doppler ultrasound has several advantages. It does not require needles, injections, or radiation, and is both non-invasive and painless. Additionally, it is a quick procedure, typically taking around 20 minutes, and is simple, safe, and more cost-effective than other diagnostic methods.
