Cardiovascular Ultrasound

True Blood Volume Flow: Method and Clinical Applications

Sunday, March 30, 2025
3:30pm – 5:00pm .
Location:Orange
CE: 1.5

Clinical blood flow imaging is very common, yet true blood flow is almost never measured. Surrogate measurements like RIs, SD ratios, and velocity are often substituted. It is now possible to measure true blood flow in ml/min. The method is robust, angle independent, and easy to perform using 3D probes. We will show how the method works as well as specific applications such as in obstetrics, liver/TIPS, carotid and peripheral arteries, and neonatal brains.

Learning Objectives:

  • Recall how blood flow is measured using 3D ultrasound, and how the method is an improvement over the present techniques.
  • Understand how flow measurements can be made to assess TIPS function, assess carotid blood and peripheral arterial blood flow, assess flow to the neonatal brain, and use flow measurements to diagnose pre-eclampsia and fetal growth restriction. They will see how these are major improvements over blood flow assessments using velocity measurements.
  • Present and perform volume flow scans on equipment in which the method has been enabled.
