Duplex ultrasound is a medical imaging technique that uses sound waves to create images of the structures within the body. It combines two types of ultrasound, namely, Doppler ultrasound and conventional B-mode ultrasound, to evaluate blood flow and structure of organs and tissues. Doppler ultrasound measures the speed and direction of blood flow in vessels, whereas B-mode ultrasound produces a two-dimensional image of the tissue being examined. Duplex ultrasound is a non-invasive and safe imaging technique that does not involve exposure to ionizing radiation, making it a preferred choice for many diagnostic applications.
Uses of Duplex ultrasound
Duplex ultrasound is commonly used to diagnose and monitor conditions such as deep vein thrombosis, arterial occlusive disease, varicose veins, and other vascular disorders. It can also help in assessing blood flow to the kidneys, liver, and other organs. Additionally, Duplex ultrasound is used to guide various medical procedures, including biopsies, drainages, and placement of catheters.
