Duplexonderzoek

Duplexonderzoek is a Dutch term that translates to duplex ultrasound. It refers to a non-invasive medical imaging technique that uses ultrasound to visualize the flow of blood within blood vessels. This method combines two types of ultrasound: B-mode imaging, which provides a real-time cross-sectional image of the blood vessel, and Doppler ultrasound, which measures the speed and direction of blood flow.

The B-mode component allows physicians to assess the structure of the vessel, identifying any abnormalities such as narrowing (stenosis), blockages (occlusion), or dilation (aneurysm). The Doppler component then analyzes the sound waves reflected off moving red blood cells. This analysis reveals the velocity of blood flow and its direction, indicating whether the flow is normal or disrupted.

Duplex ultrasound is widely used to evaluate a variety of vascular conditions, including peripheral artery disease, carotid artery disease, and deep vein thrombosis. It is particularly useful for assessing blood flow to the limbs, neck, and abdomen. The procedure is painless and does not involve radiation, making it a safe and frequently employed diagnostic tool. The results of a duplexonderzoek help clinicians determine the extent of vascular disease and plan appropriate treatment strategies.
