I am not a doctor, nor am I very strong at higher levels of mathematics, I must say though that this video has been very informative to to me and easy to follow and understand a complicated subject almost down to layman's terms. I have been very interested in DTI since I have been on a journey of discovery about myself. I am 60 years old and only in the past 1y 6m have realized that I am very likely to be on the ASD. I have found out that DTI's can be used to reveal autism in children with a high precision of accuracy. I am hoping that those same stats will hold true for an older adult. I have been in the process of finding a doctor and a facility that performs such testing. Thank you for this video as it has given me a bit more hope that other medical professionals will see it and find out that it is an extremely safe, non-invasive way to study the inner workings of one individuals brain. Thank you again!!!
ok, where were you 40 years ago when i took discrete mathematics in college? Where!? Matrix Algebra was wicked confusing and you made it simple along with an application that is totally remarkable and bordering on magic... Thanks!
just wish we could get insurances to cover these better for TBI survivors like myself. injury decades where MRI and CT are normal but QEEG showing deficit
Hi, thank you for this video. Do you think this method could be used to study the neural origin and mechanism of phantom limp pain as it could possible show us the flow of information between different neural networks?
Hi Dr Klioze! Thank you so much for your videos, they are so helpful! I was wondering if you had plans to make one for Quantitative Susceptibility Mapping? :)
Can water diffusion explain how reflexology work? For example, if someone massage my foot, I feel it in my brain. Maybe dynamic of water in the brain is affected when we do a pressure on water diffusion fibers in foot.
The grey matter is basically the axon cell bodies which, if normal would demonstrate isotropic diffusion. Since the flow is symmetric in all directions, tensor analysis would basically give you a spherical ellipsoid which really would be meaningless in a tractography reconstruction. Besides, we can see the pathology of the grey matter very well with standard MR techniques. Remember, with tensor analysis we're demonstrating the anisotropic diffusion of hydrogen protons through the brain which would infer the path of the axon bundles. Does that make sense?
There are many factors that affect regional tissue fluid content including your state of hydration, the integrity of the arteries and veins carrying blood to and from the regional tissues, a functional lymphatic system and abnormal oncotic pressures (various solutes dissolved in the blood like proteins and minerals that draw fluid into the vessels for recirculation and eventual elimination from the body by the kidneys). So, the short answer would be no. Not a specific disease but a combination of factors could definitely affect regional tissue fluid content. Does that answer your question?

Never heard a more clear and down to the point explanation of these matrix algebra concepts!

Thank you again!!!
Marvellous explanation, Dr. Klioze. Thanks to you, I've finally been able to grasp DWI and DTI key concepts.
Excellent!!! Finally, Tensors seem friendly to me thanks to your inspirational video!

Thank you so much! I was struggling so much with understanding of DTI. Your video saved me! 👏
This mini class.... just awesome. THANK YOU!
the most underrated youtube video !
Excellent detailed presentation!
You are the best! Great tensor explanation!
Thank you for helping me to understand concepts and for saving my grade in my first year seminar :)
I understood fundamental things and it's very useful video 👍👍
BEST. CHANNEL. EVER
Thanks! looking forward to the explanation of HARDI!
Nice explanation! thanks for the video!
This video was incredible, thank you so much!
You explained it perfectly. Thank you
Bravo! Fantastic explanation!
U just nailed it... Awesome video thqs 👍🏻
just wish we could get insurances to cover these better for TBI survivors like myself. injury decades where MRI and CT are normal but QEEG showing deficit
very explanatory tutorial on DTI
This is just... so awesome.

Thanks for the great class. A question: are the eigenvalues of matrix 5,7,3 correct? Redoing the calculations I found 5, -2 and -1.
Hi Dr Klioze! Thank you so much for your videos, they are so helpful! I was wondering if you had plans to make one for Quantitative Susceptibility Mapping? :)
Absolutely fantastic content. Where'd you learn all of these computational illustration skills Dr. Klioze?
So amazing Doctor
amazing video!
i really wish i had this video during calc 3
Thank you so much it's very helpful for me 😊
very informative, good job!
Amazing video
amazing content, thank you!
This is extremely helpful, thanks a lot :)

Amazing, thank you!
Bruh... 🤯 Needs a link or annotation to the first video that's referenced tho
Great video! Does DTI only show white matter tracts or can it show grey matter direction as well?
The grey matter is basically the axon cell bodies which, if normal would demonstrate isotropic diffusion. Since the flow is symmetric in all directions, tensor analysis would basically give you a spherical ellipsoid which really would be meaningless in a tractography reconstruction. Besides, we can see the pathology of the grey matter very well with standard MR techniques. Remember, with tensor analysis we're demonstrating the anisotropic diffusion of hydrogen protons through the brain which would infer the path of the axon bundles. Does that make sense?
Yes thank you.
YOU ARE THE BEST>>>>>>>>>>>3
I wish I could have seen this earlier.
thank you
Is there any disease in which water starts to recede from some body structures?
There are many factors that affect regional tissue fluid content including your state of hydration, the integrity of the arteries and veins carrying blood to and from the regional tissues, a functional lymphatic system and abnormal oncotic pressures (various solutes dissolved in the blood like proteins and minerals that draw fluid into the vessels for recirculation and eventual elimination from the body by the kidneys).
So, the short answer would be no. Not a specific disease but a combination of factors could definitely affect regional tissue fluid content. Does that answer your question?
@@DoctorKlioze Yes, thank you.
omg, i understood eigenvector.
I bet whole body is structured from fibers like in picture on 2:10
