Duplex Ultrasound for Deep Vein Thrombosis
Duplex ultrasound involves using high frequency sound waves to look at the speed of blood flow, and structure of the leg veins. The term "duplex" refers to the fact that two modes of ultrasound are used, Doppler and B-mode. The B-mode transducer (like a microphone) obtains an image of the vessel being studied. The Doppler probe within the transducer evaluates the velocity and direction of blood flow in the vessel.
For example, a carotid duplex scan may be performed to assess occlusion (blockage) or stenosis (narrowing) of the carotid arteries of the neck and/or the branches of the carotid artery. This type of Doppler examination provides a 2-dimensional (2-D) image of the arteries so that the structure of the arteries and location of an occlusion can be determined, as well as the degree of blood flow.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
Our treatment programs are designed for you. Visit one of our clinics to make an appointment.
