An intensivist who struggled to gain knowledge of mri brain beyond DWI. Appreciate one of the best lectures I listened to .

[@ShanyarHawrami]

Sir, you are a master at teaching radiology. Excellent job. Please keep up the great work.
The anatomy explained here is just amazing.

[@samirsabree5581]

I’m a Neurosurgery resident and have forever been looking for a concise overview of brain MRI sequences. This video is exactly what I was looking for. Besides, you have a good sense of humor, the BBC news sound-clip for inside tip was pretty funny. Also, I laughed when I saw the SHITHEADS mnemonic for DWI sequence. Thanks a lot. You’re amazing.

[@neuroradish]

I'm sure the mnemonic is pure coincidence. 😉 Glad it's helpful.

[@sheenaali3615]

i have looked for so many videos explaining just the basics about a MRI. This has by far been the best explanation I have ever seen! i wish I came across your lovely video during my Neurosurgical training! Never have I ever enjoyed brushing up my basics so much before Sir! Thank you!

[@wisemongol]

This is a brilliant overview, thank you!

[@ahmarinzahid2799]

Amazing lecture. I was completely lost before watching this video. Now i feel like i know the basics enough to start

[@sangilhan4073]

Thank you so much from South Korea.

[@vickysongjnvickysongjn8881]

This is the best tutorial I had viewed ever! Thank you so much!

[@anhan0007]

Excellent for neurointensivist!!!

[@drmkm6075]

Wonderful lecture, please continue posting such lectures. Thanks a ton Sir.

[@passenger.6996]

4:19 vertically it reads "shit heads" 😂😂 good lecture btw. 💪🏽❤️ Thank you for this. (:

[@sankalpprabhu8718]

Thank you for making such a simple, comprehensible and yet complete video for anatomy and search pattern in brain MRI!

[@pramilaseetha7086]

Very lucid presentation. Thank you so much for you made it very simple.

[@user-kk7os2hq2e]

Thanks you so much! I've just started to learn brain MRI and this lecture was really helpful, especially anatomy described in such nice way.

My MRI is for checking my ears, and balance glands and my seizure activity and any other abnormal spots

[@user-wr9ks3tf4n]

Hello doctor again, can I ask whether brian tumor signal intensity exhibit by FLAIR, explain by just CSF TR/TE? or also the fluid speed(fast/slow flow fluid) ? For example, if a cystic lesion expressed hypodense on FLAIR and hyperdense on T2WI, does that just mean that the fluid TR/TE in cyst approximate that of CSF, or should we also considered the fluid flowing speed? thanks

[@neuroradish]

@黃紹閔 Hi, sorry didn't catch your question earlier. If a cystic lesion is similar in signal to CSF (bright on T2 and dark on FLAIR), then yes, it has to do with its T2 property in that TR/TE is same or very similar to water, allowing it to have FLAIR signal suppression. It is not due to fast flow. In theory, if you have a FLAIR hyperintense fluid structure that is flowing rapidly (can't really think of a good example in pathology), then you can have loss of sign ("flow void) too and will appears dark on FLAIR sequence.

[@user-wr9ks3tf4n]

Very thanks for your video, I have the MRI physics of T1,T2... perfectly through your lectures. Can I ask doctor do you recommend any video or books have lecture on MRI and CT of neck? Thanks.

[@joewalsh1054]

Did anyone else notice that the list for "Beyond stroke" says Shitheads?🤣

[@efawscuba610]

I like the Sh*t heads acronym :)

[@neuroradish]

I'm pretty sure it was just a coincidence, but they're definitely bad diseases. You know, bad stuff.

[@amaebarnes]

What does slightly high t1 signal in globus pallidus extending to cerebral peduncles mean? Does anyone know? Does high t1 signal refer to a certain type of damage? Such as lesions or atrophy or hemorrhage or something else? I've tried to research but it seems to be kind of a broad term...as someone who knows nothing about this stuff

[@neuroradish]

If you're referring to a normal MRI (17:14), that slightly brighter T1 signal in GP compared to the adjacent putamen is due to myelin. GP is more myelinated compared to relatively unmyelinated structure like putamen. Which is also why it looks darker on T2 (27:49), as well as GP looks more "pale" on gross anatomy specimen compare to putamen, I believe. If it's a lot brighter, then it is probably pathologic, or due to increased calcification / mineralization deposition.

[@amaebarnes]

@@neuroradish Thank you for responding! It was a normal T1-weighted MRI without contrast...I hope I'm saying that right haha. So if GP is already myelinated but the MRI found that it is a "higher t1 signal" than normal range or whatever. Does that mean MORE myelination?
The reason I ask is because my neurologist had ordered the MRI due to her suspecting MS. But that's DE-myelination as far as I understand. So that would be like the opposite, it sounds like.

[@jorgetasse]

Gold right here
