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.

very good

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!

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.

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 3 ай бұрын

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

@nookenieminen5826 3 ай бұрын

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.

@nookenieminen5826 3 ай бұрын

@@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.

@serifo26 3 ай бұрын

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 ?

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.

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 😃.
