MRI - TOF - POST-PROCESSING

MRI - TOF - POST-PROCESSING
Today, I'm thrilled to demonstrate how I run a 3D TOF. During this video, I will also showcase the post-processing part using XA software on a Siemens scanner. Don't miss out on this opportunity - tune in and join me to learn more.

[@monirmotaharian]

very good

[@Shifty_Bravo]

I angle like image 2 (AC/PC line). This was how we did it with CTAs too. Also, our radiologists require us to scan lower to include the basilar/vertebral arteries, and include the anterior cerebral arteries. It's pretty much the entire head. Thank you for the video!

[@Nguyen_MRI]

Thanks for the input ☺️

[@dzmitryhaviazheu5199]

Great information and beautiful explanation! Thank you Bac as always!

[@Nguyen_MRI]

Thanks for kindly words.

[@pravinmajarkhede7252]

Yes image 1

[@armenmarkarian8358]

I set my TOF like image 2 that you eluded to. Thank you so much for another excellent video, Bac ! I really enjoy, appreciate and learn so much from your teachings. Blessing to you for taking the time to help others.

[@Nguyen_MRI]

Thanks for kindly words. ☺️

[@johnmac4231]

Amazing.. informative video. Thank you.

Hi Bac I use to angulate the other way around , just to put the plane perpendicular to the flow of the vessels, avoiding the void artifact. It's an average to the flow direction of arteries. but I will do that experiment with diferent angulations;)

[@Nguyen_MRI]

Thanks for sharing your input. Very interested. It's strange just a "small" thing as angulation and yet we do things so differently ☺️

[@nookenieminen5826]

Ideal angle in 2D&3D TOF is 90 degrees to flow (slice/slab perpendicular to flow), otherwise blood flow is too long inside a slice or slab and it get's too much RF and get's saturated> signal fades (in plane saturation).. Of course techniques like Motsa and tone helps.

[@Nguyen_MRI]

@@nookenieminen5826 indeed. How do you do it in practice?

[@nookenieminen5826]

@@Nguyen_MRI Much less angulation, almost straight, but of course there is always some arteries that are flowing too much time in slab. Years ago it was more angulation, but now when seq's are faster, more straight and more slabs.

[@Nguyen_MRI]

@@nookenieminen5826 thanks for your input 👍

[@collinsm.2168]

Nice video. I've learnt more about post processing from the MIP thin side. Thanks @Nguyen_MRI.

[@Nikitri3]

I angle parallel to the hard palate in order to be perpendicular to the carotid...

[@Nguyen_MRI]

Thanks for your input. ☺️

[@serifo26]

Here is the question, you can do with no anglulation or with some angulation that you always will have artifacts due to the curve of the vessels loosing the direction of the flow of the blood , causing to a decrease of nucleons inside of that slice that are excited . Once the plane must be perpendicular to the direction of the vessels flow. Right ?

[@mehfil-e-imroj]

Please make a video on acceleration factor And specially focused on GRAPPA , SENSE ,SMS , AND SEPARATE TSE FACTOR ,

[@wojciechbrynczka5574]

Line going from genu and splenium, just like regular brain 🧠

[@naftali8214]

Thank you! Can you please show us how to do MRA Neck (Carotid) and post processing (MIP). Thank you very much!

[@aymanmuhammad1610]

Great job Can you explain video MRA without contrast upper limb؟

[@blorbiecke]

We do ours the second way

[@dharanikumar.p9239]

Slab includes the distal ACA by angulation...? 🤔

[@izharkhan1549]

Please upload more videos of this software I think this is the latest version in Siemens. thanks

[@Nguyen_MRI]

It's the latest yes.

[@izharkhan1549]

​@@Nguyen_MRI could you please upload brain MRS post processing ?

[@Pendergeist]

Hi Bac Do you use any image filters i.e. sharpening on this sequence?

[@Nguyen_MRI]

No i dont think so.

[@dvalled18]

Bac, do you usually use compressed sensing on your TOF routine protocol?

[@Nguyen_MRI]

Yes when ever i can. Do you?

[@dvalled18]

​@@Nguyen_MRIyes, we usually use a tof sequence with an acceleration factor of 6 with great spatial resolution in 3.30 min with our Vida

[@hunnymun1]

Hi, Bac We do image 2 for tof angulation.. Do you hv any specific reason to do angle with image 1? Really curious~ 🧐

[@Nguyen_MRI]

very good question. i was taught like this since i started working with mri. nonethless. i tested both image 1 and image 2, i can see that with image 1 i get more of the superior part of circle of willis.

[@hunnymun1]

I'm gonna try your way next time👍 @@Nguyen_MRI

[@ryantee5138]

Any specific reason why you prefer to angulate like image 1? Just out of my curiosity. 😊

[@Nguyen_MRI]

very good question. i was taught like this since i started working with mri. nonethless. i tested both image 1 and image 2, i can see that with image 1 i get more of the superior part of circle of willis. how do you do it?

[@collinsm.2168]

Hi Bac@@Nguyen_MRI. I do mine without angulation. However to get the superior portion of the COW, I increase the number of stacks just to cover more area. Penalty? Yes of course! Increased scan time 😃.

[@Nguyen_MRI]

Always something with mri isn't. Trade off🤣

[@mehfil-e-imroj]

Non of that 😅

[@laalialabed6552]

hello can you give us subtitles in French Thanks
