duplexDopplerultraäänet
DuplexDopplerultraäänet refers to duplex Doppler ultrasonography, a noninvasive imaging modality used to evaluate blood vessels and blood flow. The technique combines B-mode gray-scale ultrasound, which visualizes anatomy, with Doppler ultrasound, which assesses the movement and speed of blood within vessels. The term duplex indicates that both structural imaging and Doppler data are acquired simultaneously.
Principle and technique: A transducer emits ultrasound waves to generate real-time two-dimensional images of vessels. Pulsed-wave
Clinical applications: DuplexDopplerultraäänet is widely used in vascular medicine. It evaluates arteries for stenosis or occlusion
Advantages and limitations: It is noninvasive, radiation-free, and provides both anatomy and hemodynamics in real time.
