Doppler Ultrasoundĭoppler ultrasound utilizes the Doppler effect. Learn more about both Doppler and duplex ultrasound below. Duplex ultrasonography takes it a step further by providing additional information about the surrounding tissues. Doppler ultrasonography gives the user information about the direction, speed, and turbulence of blood flow. The information from each scan also varies. Duplex ultrasonography provides this same image, plus a two-dimensional greyscale image of surrounding tissues. In regards to images, a Doppler scan produces a color image of blood flow. The differences are found in the images and information collected by each. They are both types of ultrasound, meaning they are both non-invasive studies that use high-frequency sound waves. Duplex: The Differencesĭoppler and duplex technology work in the same way. Get a better understanding of the types of ultrasound out there, and find the best fit for your healthcare practice. Learn more about the differences between Doppler vs. There are also a variety of Doppler ultrasound types. On the other hand, Doppler ultrasound utilizes the Doppler principle to measure the velocity and direction of blood flow. Healthcare professionals use each type to analyze different areas of the body. There are many different types of duplex ultrasound, including carotid, renal, arterial, and venous ultrasound. The result is live, high-definition pictures of blood flow. Duplex ultrasound combines both traditional and Doppler procedures. In fact, duplex ultrasound is a type of Doppler ultrasonography. duplex, it’s important to note that they are closely related.
