Researchers aim to implement a clinical strategy to monitor vascular conditions such as restenosis and thrombosis after vascular reconstruction procedures. Conventional ultrasound probes are rigid ...

We studied whether abnormal umbilical artery (UA) Doppler flow velocity waveforms occur with higher frequency in monochorionic diamniotic (MCDA) twin gestations with discordant fetal growth and ...

A recent prospective observational study published in the Indian Journal of Chest Diseases and Allied Sciences in July 2026 reveals a quick, highly accurate bedside approach for treating ...

This special structure creates a unique ultrasonographic appearance as described by Zalel and colleagues. [3] The typical sonographic appearance of the LNG device includes (Figures 1 and 2): Detection ...

The Indus Doppler Flow Velocity System is a high-frequency, real-time pulsed Doppler measurement tool with built-in data processing software intended to assess small animals' cardiovascular health.

Coronary flow reserve (CFR) is a key sign of coronary artery disease, namely how the coronary arteries that feed blood to the heart may adapt to various physiological situations such as exercise, ...

What is Doppler Ultrasound Scan? Ultrasound is a high-frequency sound that you cannot hear but it travels through fluid and soft tissues. However, it bounces back, or echoes, when it hits a more solid ...

The Doppler effect, discovered in 1842 by Christian Doppler, is familiar to most of us; stationary observers of waves such as sound waves will see wavelengths that depend on the relative motion ...

Left: 3D power-Doppler volumes overlaid on anatomical volumes of the myocardium in the left-anterior descending artery. Right: Absolute flow velocities estimated by 4D ultrafast ultrasound flow ...

While commonly associated with pregnancy, Doppler ultrasound is also used to investigate conditions such as leg pain, swelling, varicose veins, blood clots, peripheral artery disease, and stroke risk.
