MRI physics overview | MRI Physics Course | Radiology Physics Course #1

[@shanaw9582]

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.

[@radiologytutorials]

Well done!! Thank you for such a lovely message - made my year already 🥳

[@AfiOye]

Congrats. I take mine in October and I want to go straight into MRI

[@sandraaa.13]

congrats! i take my exam in july

[@rakshajain734]

How u get arrt??

[@ermaandlee4eva]

Congratulations ❤🎉🎉🎉🎉 .. quick question how much of this are they going to want you to know on the exam?????

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!

[@kdka4896]

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.

[@radiologytutorials]

Thank you so much. You've just made my day. Well done on passing your FRCR Part1! It's an incredible achievement. The hard work has paid off. Thank you for taking the time to come back and write such a lovely message

[@NA-pn5ic]

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❤

So happy to be able to help. Thank you for such a kind message ❤️

[@ronymugendi3901]

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

You’ve got this Rony 💪🏼

[@naukadladzieci]

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!!!

[@radiologytutorials]

Thank you Nauka! I just love learning and teaching. Wouldn't care if no-one was watching 🤷‍♂

[@aravind6742]

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

[@lindseyyy_h]

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

[@jillianmyers2739]

Dr. Nel, Thank you SO MUCH for these amazing tutorials. I'm a veterinary radiology resident preparing for my preliminary boards and your X-ray, ultrasound, and MRI physics videos have been so helpful. Thank you for your incredible way of explaining these concepts and for your awesome graphics! I really appreciate the time and effort that was put into them, I recommend you to all of my resident mates!

[@johnandrheyabordo644]

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!

[@dereksocomd]

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

[@radiologytutorials]

You’re a legend mate 👌🏼

[@shanaw9582]

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.

[@radiologytutorials]

That’s great to hear! I’m so glad 🙂

[@katieashley9993]

I just took my ARRT MRI registry yesterday and passed with an 89!! I started my studying by watching your videos and I can’t say enough how much they helped me understand the physics!! Thank you!!

[@radiologytutorials]

Ah that’s great news! Well done 🙌🏼🙌🏼

[@Seli6358]

This is just soo much, I am always worry of any physics , im not understanding yet, but this guy teaches so well, I know I just have to watch this first few videos a couple times, bro thank you for not trying to be one of those annoying overcomplicated professors who think they know it all. Bless you !

[@sageof6pandas233]

Im completely new to this science and am considering a career as an MRI technologist, this science seems so genuinely fascinating

[@viviscolorfulescape6865]

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.

[@radiologytutorials]

Wow! That’s dedication 🙏🏻 I’m so glad it was helpful. Let me know how you get on with the future videos 🙂

[@brushwork_journey]

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!❤

[@radiologytutorials]

Wow! Thank you so much Pang-Yen. I hope the rest of the videos help to cement your MRI physics knowledge 🙏🏻

[@quintenmking]

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

You gave me a better understanding of MRI than my professor at one of Scandinavia´s most "prestigious" universities. Well done sir.

[@utsavganguly6629]

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!

The degree to which molecular mobility is impaired. 2. The sensitivity of the sequence to Brownian motion 3. T1 relaxation time 4. The direction of water diffusion 5. T2 relaxation Time The instructor is stating that 1,2,3 is correct. But the research I conducted states 1,2, and 4 is correct. Can you help with this and explain why?
