Introducing MRI: Flow Effects (42 of 56)

www.einstein.yu... - The forty-second chapter of Dr. Michael Lipton's MRI course covers Flow Effects. Dr. Lipton is associate professor radiology at Albert Einstein College of Medicine and associate director of its Gruss Magnetic Resonance Research Center.

"Is that clear?"
"No" 😂😂😂
Amazing professor! Thanks!

There should be +2 units of change at TE (37:15), not -2.

[@roycolton4537]

obviously mistake, (-1) + (+3) just mathematically can't be a (+2). surprising how nobody ever commented on this.

Area explanation using the integral formula can be found at the image in the link below:

Thanks Dr. Michael Lipton's, i am seeing the video, is fantastic.

I don't get why at 46:26 the amount of phase shift with double the gradient pulse is -6 and not -7.
With double the gradient i should have a -8 shift in phase, compensated by the +1 of the beginning --> -7 in total.
Where am I wrong?
For the same reasons, in the third interval of time it should be +9 compensated by the previous -7 --> + 2 total at the end

[@maramsada8279]

how did he get -2 phase shift for the flowing spins during TE?

[@dr.adrianoliguori]

@ 48:30 is that why the IVC has sometimes high signal and sometimes low signal on chemical shift sequences?

[@vijaymittal7998]

thank you for clarification, as always!

[@angel13061987]

Since we can create gradients in any angle we desire by combining x,y,z coils isn't it possible to mitigate phase-misregistration-artifact by simply setting the phase-encoding direction perpendicular to the vein/flow and the much shorter freq.-encoding parallel to the flow?Thanks!

[@aminadan9029]

at 49:21, shouldn't odd echo have an odd number (5,15, 25 etc) and even echo a even number (10, 20, 40, 100 etc)?

[@dr.adrianoliguori]

Just fantastic!

[@nerminahmedali6356]

Awesome

So cute to watch physician struggle over some basic math.
