I´m a radiologist for 22 years and I am quite surprised by how clear the explanation was. I will use it in my course graduation classes of medicine. Congratulations!
Exactly 💯
thanks for the explanation. Im a biomedical engineering student and you detailed out the explanation so clearly, so i was able to grasp it instantly !
Such a thorough and clear explanation of the different sequences. I’m cross training into mri from ultrasound and this really helped!
Very well made video. Concise and clear with a soothing well paced voice that does not put one to sleep. Excellent quick intro or review for anyone.
I`m neurolgist for 20 years now and I`m really impressed by this, so clear, well sorted and pragmatic for every in house neurologist.
Basic algorhythms are needed to work in a stable solidity, even at 3 am, deeply sleep deprivated.
Nice to meet you! I'm a Radiologist. I'm also impressed.

EJStormful I need a review for carbon monoxide poisoning
EJStormful hi can you tell me if a mri scan can detect small brain Aneurysms ?
Awesome !!!! I have learned so much I was struggling to understand the basic difference between the different sequences of MRI. Please keep on uploading more brain imaging.
Thank you so much. This is the first time I got hang of mri sequences cause of your clear and effective explanation.
I have nothing to do with medicine in my daily life, but I was curious about the tech and details behind MRI machines. Stumbled upon this video and actually learned something, very nicely explained! :)
ok tell me the main difference between T1 & T2
I’m a chiroPRACTIC student in Florida studying MRI readingS. Thank you very much. It was very helpful!
@Agustin
Sir can I send you my mri images
Through gmail
You did a great job comparing the other types of MRI scans.
Hi...This is a masterpiece presentation within the shortest time possible am able to grasp something great concerning T2/T1 weighted images of the brain. Thanks a lot.
OMG, I'm a medical student in Brazil and I'm very impressed with your explanation. very good
those are very hard concepts to understand
I was struggling with understanding MRI sequences and i generally don't like commeting,but i had to express gratitude! this is gold and the go to video for an MRI noob! Thanks
Sir, your explanation is easy to grasp and besides your voice is clear which makes the concept a hell lot easier. Thank you 😊
Thank you sooooooo much for the clearest explanation.
It is very helpful.
Radio tech student from India ..... Your video is very knowledgeable thank you
Thank you!!!! This lecture is so clear and straight forward
Thanks ,That was great,I'm a biomedical engineer and I Found that really helpful.
amazing video!
It helped me a lot for my recent university exam (biomedical strumentation)!
Waiting for part 2!!!
I love your videos !! just starting mri classes makes perfect sense the way u explain it
i am an MRI student and you explained it very well i was so confused.
thank you !
Am a junior MRI technologist.Thanks prof for this useful info.
You should make more videos on MRI...starting from basics to differentials of lesions esp the brain. Will be useful to lot of us
*☼ i looked at all the people saying they were neurologists, and presumed they were confederates:* but i am a cognitive neuro undergrad who worked 7yrs diagnostic med (mostly CT/MRI) thru school, before grad methodology, MSc psychiatric & Master of Medicine (where i still am): this is as good as is claimed! except fatSat will suppress fat images on T2 - otherwise fat will also be bright. but otherwise - pretty great! i wish it had BOLD and a couple mins on pet/mri etal, but this pretty much has it all. if there is one for msk *shrugs* there is not too much missing of the core (keeping out of the quantum/atomic realm). condensing things is not as easy as people think. very impressive.
Great lesson. Thank you so much. I hope that you will have many thoughtful lessons.
This video is great! I'm getting ready to take my registry soon, and this is a great review. Thank you!
Man hats off..my head was hurting trying to cramp these imaging studies up..but u my friend explained it so smoothly...please do video on other modalities..CT MRI X ray doppler flow Usg all of these uses , advantages and disadvantages pleaseee
Thanks a lot for this fast lecture
Really nice explanation of MRI images. Thanks for sharing
thank u sir i am bpmt student (bachelor of paramedical technician) it is very help ful for me, thanks a lot sir
Like your way to explain !! Please more lessons about spine and knee mri
Nice explanation (even better if there was no music to distract)....
Thank you for this video. Please keep making great content.
With your help, I reviewd my own mri images and the information about different sequences was extremely useful. However, I do not have GRI stack. There are also Mag, Pha, mIP and SWI stacks not covered here. I guess these ones are not that commonly used. Thanks!
Thank you for this...detailed and concise
u r awesome in explaining.very clear
Wooow,,,,u guys did absolutely stunning explanation
thank you for explaining this, great job!
Thank you for this. It’s really helpful!
So educated, amazing 👍
Hi, i'm Radiologic imaging Student from Indonesia 🇲🇨
halo, kukira dari Indonesia gaada yang nonton juga
Hello suggest me book for radiographic questions
I am a MR tech and love this!
Thank you very much for simplification I really appreciate that
Thank you very much for your very informative video. As we did not touch this topic in my medical school, I am very grateful. I have 2 questions, however:
In your T1 sequence you mention fat is bright. This is reflected in that the white matter is lighter than the cortex. However the Basal ganglia, i.e. grey matter, seem to be brighter than the white matter tracts. Could you (or someone else) explain this?
Secondly, you added the correction of fat being bright in T2 like it is in T1. Did you use fat suppression or saturation in your examples (as your T2 sequences indeed show darker white matter)? Than you in advance.
hi there! Have you ever done something about the sequence in and out of phase? Thank you
Simply brilliant:: great job
Beautifully explained. I hope you have more videos uploaded.
Regards from Pakistan.
Very well done. Thank you so much!
Thank you.. great work.
my name is zainab from kurdstan your video is very very usfull for my research that was about mri thanks for your video hope you best
Could u pls explain me abt sequence t2 tirm? That is included in inversion recovery sequences
Thanks buddy, u just helped an intensivist
Very nicely explained.
Great job in this video.
This helps a lot! Thank you
very helpful. well informed
amzg.... u explained so well thank you so much
Nice demonstration
Hi, great video. In terms of MRI functionality and time sequence of imaging, are T1, T2 and FLAIR images all taken at the same time, or are patients told to lie still for three separate sets of images? Thanks!
these would be performed as separate sets of of images so if you get a T1, T2 and FLAIR you will have three separate sequences with short pauses in between. Hence the slightly longer examinations times for MRI
Great Presentation
Hi! Thanks for your video! One correction: fat is bright in T2. Thank you, Lisa
Fat is sen bright in T2 Fast spin echo not on T2 spin echo, I think there is a misconception presented here
Great explanation! "...this is the taco bell of MRI sequence explanations..." - I wanna steal this! LOL 😅🌮🔔This was a very useful video!!
Very helpful discription ....thank you
Thank you! Can you give tutorial about how to do the MP-RAGE sequence for Phillips Achieva please? Thank you in advance
Thanks for the explanation for beginners ...
Congratulations on de work gás helped us a lot. I would like to make a request please if possible release legend in Portuguese Brazil and would help us further, we foreign registrants. Big hug success.
thanks for the simple/excellent explanation. ~Sahar
Great video thank you.
Please sir keep making videos...
❤❤❤❤
We all are waiting...
Great video, thanks! - M4
Thx from my heart ❤️
Very nice sir really good
thank you it was very helpfull
Please explain to me one thing, if you have time. In multiple sclerosis, what is the difference between "leisure in T1" and "leisure in T2". I read somewhere that the treatment is considered ineffective if a patient has more than 9 leisures per year in T2. But what does that actually mean? T2 leisures are deeper, or "worse" than T1 leisures?
Thank you,,,, god bless you...
fantastick explaination thanks
I have no background in medical, but it's really helpful in annoying my doctor. :D Thanks!
Please correct the mistake : '..fat is dark in T2.." , By Jose Parra : In T2 fat is always bright except in sequences that suppress or saturate it
Roman Czekaj He is correct fat is dark on a conventional SE T2W but in the clinical field they use T2W FSE to reduce scan time, but it gives fat an higher signal intensity because some echo's in the ETL are starting to get T1 weighted.
How are you gong to correct someone if you don't even know. lmao
Good informative video
Thank you.. It is very nice and beautiful 🌹
It's really helpful ...as i am beginner ...Radiographer
This site really very best
Seems to be an excellent description of what is happening, but very hard to tell with the loud music.
That was awesome !! Which software do you use for slides ?
how do filming mri scan of brain and procedure.
can a non-contrast MRI detect a AVM? I was severly born premature in 80's so I'm worried I'm that 1% that has an AVM. I just had a regular MRI with no contrast for other issues with my head, what would that show? not much?
Great video. But 1 doubt. Would it be right/accurate to say that 'FAT is dark on T2'? (even though that's a way of differentiating the T1 from T2)
Ya that tripped me up... I've learned fat is bright on both t1 and t2
nice video, thanks
its very helpful
thanks
Its very helpful. Thanks..
It's so unfortunate.....u aren't uploading any videos on mri imaging anymore...do post videos on mri....it's one of the few unmet needs on RUclips...with huge fan following.
I'm a software developer and we are building medical imaging software I haven't found such useful material
I loved background music
great! Thanks a lot.
Thank you!
Many thanks
Thank you
Are there any more ?
What is isointense and meant for ?
thank you sir
Thank you for the upload. Are you a neuroIR?
can you please explain me how did you get that 3d model in black and white specturum colors please please help me that would be very helpful i was strucked in many times i used 3d slicer , i used fiji image processing tool,those every thing doesmn't worked for me @kmo1624
Only one correction, in T2 fat is always bright except in sequences that suppress or saturate it
Jose Parra In a real T2 weighted immage the fat shouldn't be bright, but because of the long scan time they mist likely use T2W Fast Spin Echo where there are multiple echo's in 1 repetition time. With those multiple echo's not all of them are T2 weighted. In the ETL the central echo is the real T2 weighted echo but left of that the echo's start becoming more T1 weighted what gives fat a higher signal intensity.
no fat,protien or fungi white in t1
In T2 fat has low SI where as fluid and blood have high SI
T2 fat>>> Dark
Yupp. Fat is white (though less) on T2
