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.

2024年5月10日 · A duplex ultrasound can show how blood flows to many parts of the body. It can also tell the width of a blood vessel and reveal any blockages. This test is a less invasive option than arteriography and venography .

2022年10月2日 · Duplex ultrasound is a specialized interpretation of ultrasound waves and an integral tool in medical diagnosis and therapy today. Duplex ultrasonography combines the principles of anatomic and flow ultrasonography to deliver …

2023年7月5日 · “duplex us”是超声成像技术还不成时代出现的一个词汇，中文通常翻译为“双功能超声”，一般是指同时能够实现两种成像模式的超声设别。 理论上，只要能够同时实现B型、M型和多普勒成像中的任何两种都可以称之为 “duplex us”，不过实际上只有同时能够实现B型成像和多普勒成像的技术才被称为 “duplex us”，当然更准确的叫法应该是“duplex doppler us”。 今天看起来， 同时实现B型成像和多普勒成像似乎是天经地义的，不过回到上世纪70、80年代，这样的技术 …

2021年2月26日 · Arterial duplex ultrasound allows you to view the arterial walls and lumen. It also records waveforms and velocities of blood flow to determine the level and extent of arterial disease. In contrast, an ABI test only gives you information about a circulation problem and the degree of disease—but not the location.

2022年7月25日 · Vascular ultrasound, also called a duplex study, is a noninvasive test. This test shows healthcare providers how blood flows in your arms, neck and legs. High-frequency sound waves create detailed images of soft tissue and blood vessels.

Duplex ultrasound is a non-invasive evaluation of blood flow through your arteries and veins. This test provides information to help your vascular surgeon make a sound diagnosis and outline a treatment plan.

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.

2023年7月15日 · Duplex ultrasound is a non-invasive imaging technique that combines two types of ultrasound imaging: conventional ultrasound and Doppler ultrasound. It is a valuable diagnostic tool that provides detailed information about blood flow and structures within the body.

2022年5月10日 · A duplex ultrasound can show how blood flows to many parts of the body. It can also tell the width of a blood vessel and reveal any blockages. This test is a less invasive option than arteriography and venography .
