Description

The basic principles of MRI velocity measurements will be explained, for the 2D method (Vz through the plane) and for the 4D flow (the 3 velocity components through time). The recognized indications of 2D velocity measurements will be given and illustrated (quantification of regurgitation and valve stenosis, shunts, etc.). For each application, the current results of the 4D flow will be also analyzed. Finally, the challenges and prospects of this method, which is currently being validated, will also be explained for the evaluation of new prognostic indices in pulmonary arterial hypertension or heart failure.

Learning Objectives

• Understand the basic principles of MRI velocity measurements and the differences with echo Doppler.
• Understand the importance of velocity and flow measurements in cardiac explorations through practical examples, as part of current recommendations
• Analysis of the potential of 4D flow in this field, which could lead to a very rapid change in the management and prognostic analysis of many cardiovascular diseases

Teaser

Question 1 : Diagnosis ??
Question 2 : Why is there a low maximal velocity through the stenosis ??
