Hey, biomedical engineer here, writing my thesis on MRI sequences. Your videos are an AMAZING visual break from all the convoluted terminology and as an ADHD who has a hard time going back and forth through heavy text to connect the dots, I really appreciate your effort! Keep up the great work!

Super nice explaination! I like this MRI course, but it seems that only the first 3 courses are uploaded, could you update the later 3 course?? Really looking forward to seeing it!

Some inaccuracies in explanations - in the enthusiasm to 'make it simple' and fast: For example, precession happens right after the application of the external magnetic field B0. That they precess IN PHASE - upon the application of an RF pulse of frequency that of the Larmor frequency - due to resonance - is the subtle but crucial part missing here... It is the "IN PHASE" that is critical.

...contd. The point is, that precession happens right after the application of the external magnetic field, and the RF signal only makes it precess IN PHASE/SYNC. It is the precession in phase, that produce a rotating transverse field, that is detectable by a coil in the vicinity...

Hello! Great video! I'm just a little confused about the position of the coil that receives the RF pulse. Is it supposed to be parallel or perpendicular to the xy plane? Because I've found somewhere on the internet that it's supposed to be perpendicular but here it looks parallel. Can someone please explain? Also I know the coil must be perpendicular to the B0 vector (then it is perpendicular to the z axis) - that's my teacher told me at least haha.

you do not require B1 in order for the nuclei to precess around B0 axis... this is wrong

Can you elaborate? I sought this video out because the ASRT course isn't explaining it in a way I get it. During the RF pulse, is the precession of the nuclei fixed on one vector 90° from B0, or is it precessing in a 360° arc on a plane 90° from B0 like I think he illustrated here?

I guess it is how you look at it... For individual protons, their precession is natural. They will wobble around B0. The protons precess when placed within a larger magnetic field albeit, in different directions (Out of Phase) The application of B1 introduces a coherence into the precession for a while (IN Phase precession) Now, without the application of B1, the nuclei are out of phase with each other, and in the larger context, their NMV will not precess. We deal with the NMV remember?

Hey Dr. Bhayana, I am an MS4 thinking of applying to Radiology in part because I have a background in Physics (BS, graduate coursework in QM). How much can an advanced understanding of radiologic techniques and the physics behind them improve one's clinical ability as a radiologist? How far could my background in physics take me in my potential career as a radiologist?
