keep going !!!

thank you so much you are amazing

Thank you. This helps me to study for one of the upcoming exams as a biomedical engineering student.🤓

The best educative lectures. Than you so much. You contribute greatly to health of people throughout the world.❤

Excellent presentation

Thank you very much, doctor. Very educational

Sir ur insta id?? plz

hi I have a question.If Releigh scatter has so less energy then how can it even reach the detector and add to noise ?

So ho that produce image

helpful. confirmed what my ortho said about lateral hoffa inflammation and how to tale medially to relieve pressure

Thank you!

super thank you

Thank you indeed for fantastic educative presentations. I really appreciate your work and effort. Please continue and let it to be free.

Ah yes even an idiot like me understood this very well... Strong force=glue Weak force=paint

Thank you for your videos, it is very insightful. I have a question about Muscle and fat tissue. why T2 in fat tissue is longer than T2 in muscle while T1 in fat is shorter than T1 in muscle? is the muscle tissue denser in fat? does it relate to lattice ability of tissue? thank you!

Hi there something I'm am a bit confused about. Would anyone be able to explain to me why 180 pulse dose not rephase the spins to the point that the phase encoding gradients effect is removed?

Excellent sir

I really appreciate your discussions, it helped me a lot. Im on my 3rd yr in residency training. I wish you also have a detailed discussion in mammography and CT physics. but overall, I really appreciate your discussions.

👏👏👏

Such a good presentation 🎉

i only have one question...Would you like to sir for my MRI ARRT exam?

You’re the best US physics teacher ever I don’t know how I thank you 🥹

Amazing 🤩

Thank you very clear instructions and straightforward ❤

Nice videos. Thank you.

amazing class. thanks

Thanks ,keep the good work up

Overall love your videos, but I think your description of T1 and T2 relaxation are a bit incorrect. At 12:49 you say that T1 relaxation (regaining longitudinal magnetization) does **not** affect T2 relaxation (becoming out of phase in transverse plane). A couple minutes later you say that T1 and T2 relaxation are completely independent of each other. T1 relaxation **does** cause T2 relaxation. Even if your protons stayed completely in phase, you would lose net magnetization in the transverse plane as you regain your longitudinal magnetization. Just think of it in terms of the portion of the vector that is in the transverse plane: if everything were lined up perfectly in the longitudinal plane, there is nothing pointing out of the plane to give any transverse magnetization. For this reason, *everything that causes T1 relaxation also causes T2 relaxation.* There are just also other ways to cause T2 relaxation (namely, loss of phase coherence). This is why *T2 relaxation is always shorter than T1 relaxation.* www.mriquestions.com/what-is-t2.html explains it better than I can. (The immediately prior and subsequent 'questions' are also pretty relevant.)

Thank you so much, such a great explanation !🎉

Life made easy.

Awesome explanation! Clear, concise and so easy to understand.

Perfect

Words are not enough to appreciate your efforts, u made MRI physics so interesting n easy, big applause 👏 🎉❤

Hello can u pls pls make videos on nuclear medicine in cardiac imaging, cardiac ct and cardiac mri Plss All ur videos are awesome..Ty so much ❤️❤️

Please do the extra questions! Love your work

Hi Michael, thank you for the excellent tutorials! I was reading about the heat bloom effect increasing focal spot size when taking multiple exposures in quick succession. Is this ever a practical problem rather than a theoretical problem now that more practices are using DR and can rapidly take images? Thank you!

Thank you

Amazing lectures through and through! I might be mistaken here, but at the 9:00 mark, didn't you mean to mention longitudinal instead of transverse?

thank you 😊

Which book is the best and easy book for radio physics??? So that we can read that book along with your videos

@9:49 isn’t it counter-intuitive that stationary spins will not give any signal although they have more potential to be in phase and so can give bright signal? While the opposite should be true for the moving spins that experienced phase shift? I am sorry I m confused… specially after going through the “diffusion weighted imaging physics” where the basic theme was that stationary protons will give brighter signal (restricted diffusion)… please help !!

Thanks such a clearly explained video.

Thanks

Really incredible videos! Even after taking official courses in MRI at the University, this has had huge educational benefit for me. Thanks so much for sharing!!!!

Good one but missing coronal,axial etc should b mention plane

Thanks Dr. micheal.
