    Thank you so much for these videos! I have a hard time learning out of textbooks and these are the best videos on TH-cam of MRI physics. A week ago I was lost and now I have confidence in passing this exam at some point 😁 🙏

      Thank you. I have no doubt you will pass the exam! I also struggle with textbooks 😣 That's the main reason I've chosen to make these. Be sure to message me to let me know when you pass!

    I really appreciate that you take the time to reinforce previous concepts in each video to further comprehension and retention. Thank you for all your hard work and dedication to helping your viewers.

    Said it before and im gonna say it again, thanks for the amazing course so far. MRI physics is made easy thanks to you.

    Thanks for your courses. I believe I’ll be fully prepared to take my ABR exam this fall. I wish there were courses on CT physics and nuclear medicine-those would have been amazing. Your question bank is fantastic too; it really challenges me to understand and remember complex concepts.

    In my opinion GRE sequences with refocusing of the stimulated Echo (PSIF, SSFP) are also coherent. They are just part of the coherent GRE sequences, just as the balanced GRE sequences with combined "FID" and "Stimulated Echo" refocusing (TrueFISP, etc.).

    This is so helpful!! I was really struggling to understand the stimulated echo from textbook diagrams so this is amazing. Keep up the great work!

      I'm so glad! That's exactly why I started this channel - sometimes the textbooks make things seem more complicated than they actually are 😆

    I think that using SSFP as a general term for GRE with echo refocusing can be misleading because only GE refers to them that way. Additionally, other coherent sequences, such as FISP or TrueFISP, are also SSFP sequences because steady-state free precession is present.

    @2:04 "Doing this, putting two RF pulses close together will generate what's known as a stimulated echo"
    This doesn't sound right. Stimulated echoes originate from 3 RF pulses. A good mechanism overview is given in "Stimulated Echoes: Description, Applications, Practical Hints" from Burstein 1995.

    the problem is you take 30 minites to say something that should take 30 seconds, and you spend so much time unnecessarily restating things that you've already said, that you don't even clearly emphasize the 30 seconds worth of actual valuable content in the video.

    • @radiologytutorials
      @radiologytutorials  ปีที่แล้ว +5

      Sorry you feel that way. Not everyone learns the same I guess. You might just get concepts quicker than others. Any specific examples so I can try improve?

      i think sometimes less is more, and just having a disclaimer at the beginning (as you already do) is better than re-stating the frame of reference (at least for me). but i appreciate your work, and i think you've done more than anyone else on youtube or elsewhere online to explain the details of this stuff

    • @radiologytutorials
      @radiologytutorials  ปีที่แล้ว +3

      @Jacob-ye7gu thanks 🙏🏻 Appreciate the feedback! Very valuable for me to get everyone’s opinions.
      It’s funny because I debated refilming this video (due to the long intro sequence). Then had three private tutoring sessions where people really struggled to grasp the difference between spin and gradient echoes. Ultimately decided to keep it in, in order not to leave anyone behind. It’s tough trying to teach a large diverse audience..

      @@radiologytutorials For someone like me who struggles with physics in general, I really appreciate the repetition and summarising what we know so far. The great thing about an online platform is being able to replay and forward sections as necessary. Really appreciate all your hard work- Thank you!
