Pretty amazing video,music helps a lot
Comment from : Prithvirajan Sridharan

Please make video on other mri sequence too 🙏
Comment from : Dr Panwar

The explanation is clear but the concept is bizarre, just little difficult to wrap my head around it
Comment from : Shanmuga SundaramB

The Cartesian coordinate schematic is utilized due the orientation of the gradient system of MR systems , x,y, and z, the three planes diffusion restriction are measured
Comment from : simsdroid

Diffusion is important because it describes the failure of water to transport across a cellular membrane, due to a pathological state, that is not clearly elaborate here

Good job!
Comment from : Anastasios Tsogkas

For to do the wavelet transform or Function Wave i am not requiere the complex number or Fourier series Just I need the new methodoly I discoveredI left this video to compare:br youtube/3Ebvypj577E

Nice job
Comment from : abdul khaliq Sahak

So CSF with higher B values will have a low signal because with a long enough dephasing and rephasing magnetic gradient CSF with its isotropic diffusuion will be just pushed way too out of phase to give any signal Proportionatly lower B values may give some more signal with CSF and more shine through, while b0 has no de and rephasing magnetic gradients, so it will essentially just be T2 CSF intensity and very sensitive to any shine through Is this assumption correct? Also, what is the difference between a b0 and an actual T2 image? Could You in theory skip the b0 if you have a T2 and just use it as b0 instead?brExcellent video btw!!

This is very nice video It make me understand more about these MRI sequences Thank you very much!!

Good Grief, that background music is so annoying!
Comment from : Rebecca FromHoneyback

After watching MANY videos on the subject, this is the first one to mention the three cartésien plains The whole time I'm thinking "How the heck do they get an image out of that!? In 3-D no less!" Now it's starting to make a little more sense
Comment from : Cyphermunk

This was like an epiphany to me Thank you so much

Beautifully explained

The best explanation of diffusion tensor imaging I have seen Thanks for preparing this elegant video

even though its a complex concept, your explanation has made it crystal clear thanks a lot

you're cool like really cool
Comment from : Anastasia

Plz cut down the music, it's annoying !!brThat will help better focus!!
Comment from : deepa pola

Great music but please lose the music!!!
Comment from : GW

Man this video really cleared things up for me regarding the difference between DWI and ADC, and why discrepancies between them is important I just couldn't understand what the difference was before!
Comment from : Tobias Knudsen

Thankyouuuuu

Music choice changed my mood 👌😂

stop the music i cannot concentrate
Comment from : kaynat khan

Great job👍👍
Comment from : Lakshika Sewwandi

This is so helpful! Thanks I'm taking some MRI grad classes, and these videos definitely help to solidify key ideas before heading into a lecture that would otherwise totally baffle me I will confess, though, that I find the music throughout a bit distractingbrbrAnyway -- thanks for the time and effort you put into this! It is a massive help
Comment from : Tone Noob

Try to make videos larger to completely clear all concepts in one video

lose the music very distracting

Really helpful!

great videos really helped me in a job interview thanks
Comment from : Fraser A

Here's a question for you Since T1 relaxation dumps heat into the patient, can you localise this effect within a tumour and use it therapeutically? It would be nice to fry tumour cells without harming the patient, and not exposing him or her to X rays!
Comment from : Mandolinic

I find your images showing precessing neutrons much easier to understand than most other videos I've seen
Comment from : Mandolinic

Do you have a website where this information is published? How can I reference this appropriately?

Doctor, this is great Thanks

Great videos (please ease up a little on the corny music ><)
Comment from : shammythefox

really helpful to understand the DWI

Well laid out, very concise, and nice summary of the important points to bring it home
Comment from : buttman20

Thank you for the video! Are you going to add one on DTI as well?
Comment from : David Ellis

Thanks for the video! I just add this explanation of why infarct appears as a decreased ADC and increased signal in DWI:br"In the setting of acute cerebral ischemia, if the cerebral blood flow is lowered to 10 ml/100gm/min, the cell membrane ion pump fails and excess sodium enters the cell, which is followed by a net movement of water from the extracellular to intracellular compartment and cytotoxic edema Diffusion of the intracellular water molecules is restricted by the cell membranes The restricted diffusion results in a decreased ADC and increased signal intensity on diffusion-weighted images"

Thank you so much This now makes more sense in my head Would you be able to touch up on the b values as well by any chance? Thanks again
