TR, TE & MRI Image Weighting (T1, T2, PD) EXPLAINED | MRI Physics Course Lecture 7

How does T1 Recovery affect our T2 Decay signal? Are TR and TE on different timelines? How do their values lead to our standard MRI sequences? What is the meaning of life? On the final lecture of the basic but not so basic series of MRI Physics Explained, we’re going to bring all the topics that we’ve discussed in the last few lectures on image contrast together and show how these parameters participate in a harmonious dance to build our standard sequences! Enjoy!

I wish my MRI physics lecturer could have explained it all this way. Watching your 7 videos has been such a break through. The way you deliver this content is so logical and these concepts of T1 and T2 weighted images FINALLY make sense to me. Keep up the great work and thank you so much.

Ich habe es endlich verstanden😃 Vielen Dank für die tolle Deine Videos sind super

[BrianStJohns]

Definitely need more content from you. I have asked myself so many of the same questions and it’s starting to click after watching your lectures. I’m going back through several more times and taking notes for sure. Would love to see how you explain pulse sequences, kspace, and Velocity encoding. Keep up the great work!

3rd year r3 resident year who's relearned this every year without fail. First time this has been explained, I've had the same questions about how T1 generates signal. Thank you so much

[kanamala]

Probably one of the best mr teachers out there. Thanks so much dude.

[karlitadr]

Thank you, I appreciate your pedagogy and humor!!🧠😂💯 KEEP IT GOING!!!

[TAHA-TOUABA-RADIOGRAPHER]

Thank you very much pro...your videos are the best I watched ever, I am not flattering, your videos are the best ever

[WalterPine]

Thank you so much, can you lecture on the parameters: fov, matrix and tr that influence time?

[Gragon]

Great stuff. please continue on with other sequences explained. TSE, FSE, STIR, TIRM, TOF etc etc etc etc

[trelaxation]

I noticed that the T1 relaxation times are constant. So does the MRI tech choose the TR time only to control TE or does the tech choose both TR and TE? I'm taking the ARRT test in December 2024

Dude, ive been trying to wrap my head around how T2 relies on long tr and te when T2 decay happens much faster than T1 relaxation...this is the only place ive seen that explains how this actually works w the T2 decay being in the graph after the first TR.
