Took my ARRT licensing boards on the 19th of this month and passed! My highest scores were in Image Production which was over half of the questions and it’s all thanks to this playlist. I was lost before watching these videos and I am so grateful to have found this channel because it was the absolute best resource for understanding the physics behind mri. I cannot thank you enough for these videos and providing them for anyone free of charge.

I am a Field service engineer for a Medical Imaging service company. I work Primarily in X-ray. I was recently asked by my employer to learn MRI on my off time to prepare myself for the MRI training schools that I'll be sent to in the closing in future. MRI is so different from my typical imaging modalities that I just had no clue where to start. I am happy to say that after rewatching this video a dozen times and looking up definitions of just about every term used in the recording, that I am beginning to gain the first layer of understanding MRI. Thankyou for producing this well thought out and organized series. Keep up the fantastic work!

Dear Michael, I just wanted to express my sincere gratitude for the excellent videos you selflessly compiled for us free of charge. You truly have a gift for teaching. With the help of these I was able to pass the FRCR Part 1 Physics exam I sat a few weeks ago, I have no doubt this was largely contributed by your videos and I can’t thank you enough.

Thank u so much...u have made physics so easy...was in desperate need of MRI physics... I wish I could give 1000likes to each of ur videos... stay blessed❤

Out of all the videos I came across with, this might be one of the most comprehensive ones! Thank you for aiding me in my study!

i understood more in this single intro video than i did taking a semester long MR physics course.. so happy i found this!

Thank you so much for your amazing videos!!! I passed my ARRT boards thanks to your lectures.

One of the most effective educators. Im really proud of you! 💯 👏🏼

First proper educational explanation video with visualisation online. We all know what it means to properly cover topics first on YT. Not sure what's your drive investing so much time for so little recognition so far but I guess fascination with educating and the fact that teaching others is the highest level of effective learning. Good luck!!!

Thank you so much for the video! It took me 3 hours to go through the 23 minutes while taking notes, but it was absolutely worth it. Even thought it´s just the overview, I already understand much more than from medschool lectures and radiology residency courses on MRI. You did a really great job! I am looking forward to studying from the following videos of this module as well.

"Thank you so much for all the hard work you put into educating us! Your passion for teaching is truly inspiring, and your dedication to helping us learn is greatly appreciated. You make learning fun and engaging, and I always look forward to your videos. Thank you again for everything you do!"

This helped me a lot to understand the basic principle of MRI ❤ You are really a great teacher , keep growing , keep teaching . Love from India 🇮🇳

Man i cant thank you enough.. You have made TE & TR so clear that i almost cried when i understood it..Thanks a lot🙏

I am relying on these lectures to pass my exams,am confident. Thank you Dr Michael

So many aha moments in this single video. You have officially rescued me from the many hours spent unsuccessfully trying to wrap my brain around these concepts. I cannot thank you enough.

I’m in the middle of step 1 review and your vids are so helpful. Congrats on your growing channel!

You are the Richard Feynman of Radiology! This is brilliant - I hope you get the career opportunities you deserve!

True Definition of the best teacher, You made complicated concept, look so easy, highly appreciate your efforts!

my mind was just blown, thank you thank you thank you for explaining this so well

Such a perfect timing! I'm taking the MRI course next semester and I can't wait to watch this series :))

You're doing a phenomenal job, Dr. Michael. I'm revisiting some of these concepts for teaching radiographers and I have to say, this is probably the best, most organised resource for MRI physics out there. Keep up the amazing work man!

thank you so much, I know this type of conteint may not provide so much views and interaction, but it is helping a lot of people. you are a very kind man thank you so much.

Beautifully explained.... God bless you with more knowledge ❤

Awesome lecture! Thank you very very much.

I'm really grateful. Your lectures are a blessing for me. Keep up the good work. Lots of prayers for you. Can't wait for more MR physics and CT physics lectures .

Thank you for all your hard work. I just passed my Radiology Board. Your Xray vids were what I started off with in prepping for. I'm now embarking on passing the MRI Boards and am starting with your videos. As some have said in comments, you and your videos are a blessing. You Rock!

Thanks a lot, looking forward to this course and the question bank.

I really appreciate you making these perfect series of videos on MRI. It helps me a lot. thank you million times. I wish you could give thousands of like for your fantastic videos as you deserve that.

Watched this channel a bunch, I passed first try back in February

Perfect! Thank you so much.

I LOVE the trampoline part!

You're such a good teacher man, I have to take my registry in a year and I can already tell your videos are gonna help so much, appreciate you

Excellent illustration of MRI imaging technique, clear and succinct even tho brief, impossible without thorough understanding of it, no wonder you are the teacher 👍👍👍

Thanks Sir for best lectures

Thank you 🎉. I have finally understand MRI physics

Brilliant as usual ❤❤❤ Keep it up!

Thank you for this. Makes our life so much simpler

amazing video series brother :) love it , super helpful and well presented

Thanks for another amazing lecture. Great animations btw :)

I am a visual learner and I need to see picture things in my head to understand it. I wish you were my teacher!:) thank you so much for the videos. Great that you numbered them too.

Superb video, very informative! You are a perfect teacher. Thank you so much.

Thank you for your excellent presentation. I think that including all of the concepts briefly in an introductory lecture of MRI make the big picture very horrifying

Best explanation I have seen by far

Thank you very much doc for your help I admire your hard work

Great explanation. Thank you for making it easy to understand

Thanks for this, i was looking for some great videos to check out before I start taking my MRI

Thanks Dr you are making our lives easier.... Lot of love

Thank you for making these tutorials, I’ve been struggling with MRI physics for 4 years, even after acquiring radiology license there are concepts that are unclear to me. But after seeing two episodes of this series, some of my previous questions were solved, and I’ll see other episodes in the following days. Thank you again for the awesome contribution!❤

Thanks, with great description.

LEGEND for all your physics videos. Thank you

i love your channel! thank u so much!

I was deperatly waiting for this video to come..thanku for adding this

Thanks a lot sir,,, I m hopeful this series is going to be very helpful for us, stay blessed 🙌

I'm taking a Neuroimaging course and this series is helping tremendously. Very clear presentations.

Thank you Sir. Also expect videos on flouroscopy, mammography and computed tomography. Bcoz i am sure your videos will solve all our problem regarding these topics. Great work. ❤

Holy crap that was good. Just started my radiology residency and the first time I read about MRI physics was a mess. But this video alone allowed me to understand what I was reading. Thank you so much!

Thank you! Just in time before my Physics exam.

Great video. Thank you! I'm slightly less worried about starting this topic at uni next week now

Can’t expressed in words ur selfless efforts and pain ur taking to make such a tough subject lucid for students. It’s next level.I think GOD been there always to bless you.😊

one of the best lecturer ive ever watched, thank you sir for spreading information and ideas

Thank you so much It was such a wonderful video as always U have made understanding physics so simple and easy.. Amazing educator

I really appreciate the analogies you used to explain difficult concepts. I had a really bad instructor for my mri physics class and this one video was more helpful than sitting in his 3 hour lecture. I look forward to more of your videos as i am preparing for mri certification exam. Thanks again for your amazing video(s) !!!

Amazing helpful lecture, thanks!

Your videos are honestly so helpful! Lol they are going to be the only reason I pass my radiology physics exam.

Incredible educator - thank you 🔥

you are truly amazing. Thank you so much. I was struggling with understanding different imaging modalities and you came to my save. Thank you

Sir u r doing excellent work ..May God bless u ❤

Thank you. Absolutely carried my way through x-ray and uss. Ready to be carried through mri

thank you for making a difficult concept make sense

Thank you very much!

Excelente explicación, saludos desde Chile

Current MRI tech student and we're going to be starting physics in a month, this greatly helps me visualize what I'm reading. This will help me greatly 👍 thank you!! Looking forward to the rest of the videos 😊

God bless u bro ❤

amazing video. very clear explanation for a complex topic

Sir hats off to u sir.such a dedicated teacher.

Learning MRI right now..Read a few chapters of my MRI book. So so many AHA! moments with your explanations! Very well done, easy to understand, all the puzzle pieces are now coming together!

Thank you so much 🙌🏻

I am not sure yet, but I think you just saved my master’s in neuroscience. I do not have a STEM background and this was INCREDIBLY helpful

Thanks you for explaining so nicely hope you can start start some online courses where we can ask doubt as well

You're videos are my week highlight 😅

Wat an amazing explanation ,,this topic was wat i wanted badly for many times ! Stay safe and blessed dr🙏🙏🙏🙏

Thank you so much bro❤

Great lectures

Ohh my god most awaited video bt lil late fr my exam......no problem i will follow all Loaded luv regards

Thank you sir.

Wow Sir I love it

Life saving !

thanks for the vedio sir

Currently doing my post grad for MRI, this will be a lifesaver and carry me through to the end!

Thank you

Thank you sir

Thank you for the very useful explanation and the nice illustrations I have a question.. I could not link these 2 statements That every atom has different precessional frequency with the statement that the applied RF pulse will have the same precessional frequency of the spins if we have many atoms and each has different precessional frequency then how come the RF will have one precessional frequency

Thank you for sharing this. You have made materials easily digestible with wonderful illustrations. I have just a question regarding the axis. Is z axis the horizontal axis or the vertical axis?

looking forward sequences videos ♥

I'm having frcr part 1 physics in March 2024 . Your videos are amazing. Bought the Q bank as well. Wish all the curriculum was here but mri is coming and hopefully more to come. Well done❤️❤️👏👏👏
