Vascular duplex ultrasonography is a diagnostic technique used to detect various vascular conditions. It helps evaluate blood flow through your arteries and veins by combining traditional ultrasound with Doppler ultrasound. Traditional ultrasound uses sound waves bouncing off blood vessels to create images, while Doppler ultrasound uses sound waves reflecting from moving objects like blood to measure its speed and other flow characteristics.
Vascular duplex ultrasonography may be used to diagnose several conditions, including:
Preparation for a duplex ultrasound is usually minimal but may include:
Here’s what to expect during the procedure:
1. Preparation: You will lie on a table, usually on your back. A clear gel will be applied to the area being tested to help conduct the sound waves.
2. Ultrasound Probe: Your doctor or technician will move an ultrasound probe gently over the examination area.
3. Sensation: You may feel some pressure from the device, but it will not hurt.
4. Sound Waves: The probe sends sound waves into your body, which bounce off blood vessels and blood, returning to the device.
5. Imaging: The information is relayed to a computer, producing live moving images on a screen.
6. Duration: The test typically takes about 30 to 60 minutes to complete.
Vascular duplex ultrasonography is not associated with any side effects and does not require any post-procedural care. You will be able to resume your normal activities immediately. The results of your study are often available right away.
By understanding the vascular duplex ultrasonography process, you can better prepare for the procedure and understand its role in diagnosing vascular conditions.
