Väridopplerikuvaus

Väridopplerikuvaus, also known as color Doppler ultrasound, is a medical imaging technique that uses ultrasound waves to visualize and measure blood flow within the body. It is an enhancement of standard Doppler ultrasound, which can detect blood flow but does not provide a visual representation of its direction and speed. In color Doppler, blood flow is superimposed onto a grayscale ultrasound image, with different colors representing different flow characteristics. Typically, red indicates blood flowing towards the ultrasound transducer, while blue indicates blood flowing away from it. The intensity of the color can also represent the speed of the blood flow, with brighter colors denoting faster velocities.

This non-invasive technique is invaluable for diagnosing a wide range of conditions affecting blood vessels. It is commonly used to assess blood flow in arteries and veins throughout the body, including those in the heart, neck, abdomen, and limbs. Physicians utilize Väridopplerikuvaus to detect blockages, narrowing, aneurysms, blood clots (thrombosis), and inflammation in blood vessels. It also plays a crucial role in evaluating the function of heart valves and assessing the health of a fetus during pregnancy by visualizing blood flow in the umbilical cord and fetal organs. The procedure is safe, painless, and does not involve ionizing radiation, making it a preferred method for both diagnostic and monitoring purposes.
