These lectures are so concise and easy to understand. Thank you.

[@radiologytutorials]

This makes me so happy! Thank you. I’m really trying to make it as simple as possible. Glad it’s been helpful 🙂

[@vanishreebalaji668]

All your lectures are great. Thank you for simplifying these tough concepts!

[@omarfarid952]

Thanks a lot for these lectures.

[@Ruban-C-002]

Sir.... such an amazing lecture ... Greater understanding of concepts ... Thankful ❤

[@ames1988]

Thank you so much for the excellent lectures! Can you also cover spin lock, T1rho relaxation, and adiabatic concepts?

[@isasacic2917]

Fantastic content! Thank you from Sweden!

Thanks @isasacic2917! Love knowing where everyone is from 🥰

[@ruviniratnayaka6234]

Great, Amazing talk. Thank you very much..

[@radiologytutorials]

So glad you enjoyed it!

[@karlmoody4891]

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?

I've been trying to understand the mechanism of action surrounding the null point in the IR sequence. And I've been trying to reconcile the quantum mechanic principle of basically having no way to know where something is in space, with the magnetic vector that can be predicted due to accumulation of many protons in their predicted state. It's helped me realize that the transverse magnetic vector is a result of the stimulated coherent precession, and that without stimulation from the RF pulse, there is no coherence. Which means T1 recovery, by nature, isn't coherent recovery, so the magnetic vector doesn't "swing back" through the transverse plane. So my question is, if my previous statements are correct and apply, is the null point essentially the quantum mechanical point in time where we have no way of predicting where the spins are, because they are, in that moment, not influenced by any external forces? And thus there is a net zero magnetic vector? Or is there a magnetic vector that still exists but no component of it exists in the longitudinal plane? Thanks in advance for your time with my questions!

[@coleenjones7531]

i understand what happens up to and including the 90 rf pulse. but what happens after? i am confused

One of thae important topics 🙏

Thanks Michael 👏

[@shawnoguri2104]

Really love all your videos, help me a lot to answer during exam.. Love from Malaysia😊🫶

[@rrozinak]

Thank you for your amazing videos. I don't understand one thing though - for the STIR and FLAIR sequences you have images with TR at 90. Shouldn't the new repetition start with 180 again?

[@mudangayu1729]

180 is just an extra inversion pulse we're using. 90 degree is the excitation RF pulse, therefore the TR is counted only from 1 excitation pulse to the next, not 1 inversion pulse to next

[@beyondrepair5616]

Thank you!

[@radiologytutorials]

Thank you for watching 😀

[@ManakSuriya]

Thankyou❤❤

[@fatimahabeeb198]

شكرا للشرح

[@mitpatel8133]

There is one small mistake at around 9 min you said when we apply 90 RF pulse we are going to loose all trans mag but we lost long mag.

[@dr.shadmbbsdphmasco]

Yup not trans mag

[@GajabSingh-v8g]

Thankyou micheal sir

[@mohsinshehzad4031]

Honourable sir Need Computed tomography physics lectures also. Thanks in Advance Sir

[@radiologytutorials]

Hi @mohsinshehzad4031- I'm working on finishing the MRI series at the moment, but hopefully CT is not too far behind!

[@dr.albertmir]

Incredible video. Thank you very much.
