About this event
In this single day event, we will teach you about the fundamentals of 4D Flow MRI acquisition and discuss several applications of this imaging technique to be used in your clinical practice. Specifically, we will teach you how to perform valve tracking in whole-heart 4D Flow MRI to accurately assess valvular flow, regurgitation and shunt flow. We will describe how to assess wall shear stress maps in the aorta and how this measure relates to pathophysiology. Finally, we will discuss clinical examples of 4D Flow MRI in acquired and congenital heart disease.

Prerecorded in-depth educational presentations will be available for you to watch at your own availability, prior to or during the workshop. The presentations will be discussed live in the morning session by the teachers. The educational presentations are also available to revisit later, for one week after the workshop.

In the afternoon session, you will gain hands-on experience of analyzing 4D Flow MRI data. In small breakout rooms, the teachers will guide you through the workflow of the analysis software and assist you with your analysis of clinical cases.

You will work on the CAAS MR Solutions platform from Pie Medical Imaging. You will receive a trial version of the software to work with at home during and after the workshop. A free 30-days trial licence will be made available. You will receive example cases or you can bring your own DICOM data to discuss with the teachers.
