Magnetic Resonance Advection Imaging (MRAI)

What is it about?

We have found that data that is acquired in functional MRI experiments to study how our brain works also contain information about how the cardiac pulse wave travels through the brain. By modeling pulse waves with advection equations, we obtain a parameter that can be mapped to get an “MRAI map”.

Why is it important?

So far, MRAI maps reproduce main arteries of the brain, but we hope (this still needs to be demonstrated in further experiments) that they also can tell us something about physical properties of the arteries, such as their distensibility. This could be important for imaging cerebrovascular diseases or risk of stroke.
