MRI Susceptibility Weighted Imaging (SWI) @ 3T

Lately I’ve been looking into SWI at 3T, how can I make the images better? I found some parameter adjustments which improves the quality. I want to share my thoughts with you.

Thanks for watching, following and support.

Hey! Great video, as always. You're doing the siemens MRI community a great service :)

Your content is really important and timely. These are of immense importance in modern MRI. I hope you will give us more content like this. Stay well. @ChandanAdhikary #From Bangladesh

You should do one on elastography. Don't see anything on that

Thanks for the useful tips. Bac would you show me more optimization on how to demonstrate the swallow tail in 1.5T swi sequence?

[ruthmathew]

I am definitely going to try this on my scanner .

[kcicilioni]

Hi, Bac. Thanks! I was wondering if you had any insight as to why the reciever/transmit bandwidth can be used to improve susceptibility artifact?

[anniesshenanigans]

thanks for this quick comparison. It is simple and easy to remember. I am adding this to my MRI fb group (private group for techs that I know).

Thanks Bac! Ill see if i can try this on 1.5T trying to optimize it to compensate for the time. I think it could be handy at least to see the swallow tail for Parkinson’s disease when 3T is not available

I tried this at 1.5T using a similar 50% increase in TE (going up to 60ms). Having such a high TE caused a more T2 appearance with some CSF starting to appear. I think it may be best utilised at 3T.

Are you going to try this out at your scanner? let me know.

Thank you for your videos. I have a technical question, we have a lot of instability using a GRE and DTI sequence which seems to cause motion type artifacts, possibly from vibrations. It's intermittent but seems to mostly affect GRE/EPI and not T2 and Spin echo sequences. Is there a setting I can tune to more this more stable of a collection?

Thanks for all videos but I like to see more training and trix about Ax30 or 50
Thanks again

Hi Bac, just to confirm, is oxyhaemoglobin always hypointense on SWI and hypointense on phase? I’ve come across literature where it seemed this could appear iso-to hyperintense on SWI as well, and now I’m really not sure about its appearance on phase… Would be grateful if you could clarify!

Hello, it’s really useful tips, but i was trying to do SWI (coronal) for the brain and I tried many time but unfortunately it didn’t work. Do u have any idea or advice to do it ? Thanks in advance

[mihaimoldo]

Hell yes, ofc I'll try it asap.

Can you also do one with dark_fluid please ?
I've heard from many that they don't like the "contrast" from Siemens, especially the ones coming from GE or other vendors.
I don't know what FLAIR contrast they want/like so...

Also when you mentioned that SWI is licensed, you should mention that instead of SWI if they dont have it they could and should use the "hemo" sequence instead.

great tips on this video. Will try it on both magnets. That true, as my teacher said "there's no free lunch in MRI" as we get good things in images (the small vessels) but more susceptibility will appears. BTW, a very good video. Thank you...

Is there any 3D swi sequence in seimens Skyra for PD patients
