MRI - CE-MRA NECK & POST-PROCESSING

Today, I’m thrilled to demonstrate the straightforward process of performing Contrast Enhanced MRA of the neck, and I’ll be sharing some invaluable tips and tricks for seamless post-processing using View&Go (XA software). Don’t miss out - tune in and join me.

Great content Bac. Dont forget to always include the aortic arch in supraaortic trunks MRA as some pathologies such as dissection or stenosis in the origin is what the angio can show vs doppler US which will only suspect but not see. We also run the venous phase with head only dedicated FOV in sagital as cerebral vein thrombosis usually gets clipped with the arterial coronal FOV of head&neck

[@Nguyen_MRI]

Very much agreed. I usually covers more when it comes to ce mra as you mention. Was just to show how it can be done easily with carebolus technique. Thanks for input. 😊🫰

[@mihaimoldo]

Great video Bac as usual! 99% Care Bolus is used because it's reliable enough for all pacients . Test bolus is ofc the most accurate method but you also lose 1-2ml of your contrast dose overall so many radiologists don't want that in the final Angio scan. Btw the TTC trick is in some cases counterproductive because when you see the first part of the contrast flooding the carotids, that's not the highest intensity signal of the entire contrast bolus, that usually is 1-3 seconds after, so for example in older pacients where the cardiac debit is lower you are too early for the arterial phase, but ofc it greatly depends on the pacient.

[@Nguyen_MRI]

Very true. Thanks for input. ☺️🫰

[@1shot-1kill84]

I learned using the Test Bolus but have been using the Care Bolus approach for years. It's great. It simply takes the guesswork out of it. You can see in real time when the contrast is approaching the bifurcation and start the scan. I've never missed one yet with carotids or in the aorta/renals/mesenteric. Care Bolus is a no-brainer.

[@Nguyen_MRI]

Thanks for input. I guess just stay calm and don't stress will do most of the work☺️🫰

[@1shot-1kill84]

@Nguyen_MRI yes exactly. Some patients blood flow rates are higher or lower than others, so the contrast may arrive a little sooner or later. It's a great tool for new techs and old. As you said, stay calm and be alert for the contrast arrival. Great vid as always.

Saludos crack, gracias a sus videos voy aprendiendo a planificar 🩻✔️

[@Nguyen_MRI]

thank you for kindly words :)

[@muralimohanvenkata5740]

Thank you for your Video, I would like to mention that the table position is fixed and you are losing signal on the arch of the aorta. Tip: add a table position strategy to ISO and care bolus copied center slice with pre contrast to avoid table movement for post contrast.

[@Nguyen_MRI]

indeed, very important. thanks

[@mihaimoldo]

You can use copy parameters : table position after the Native scan ,that way the table won't move regardless of ISO or not.

[@Nguyen_MRI]

@@mihaimoldo yes important so the table won't move when you want to start the first arterial phase. Nonetheless using the pre protocol of Siemens is a good start 👍. Thanks for input as always.

[@JRGeronimo143]

Hi, just wanna ask on how can we plan the right trigger? And to not prolong the scanning time while using the trigger.

[@user-hx5zv7xe9h]

yes of course i like it thank you again !

[@muralimohan24]

Thank for the vedio. Great content

masha allah you are the best

[@ubaidullakadaba]

Thank you very much Very useful knowledge

[@frankiechankf1]

thank you very much,very useful

[@Gun1ld]

Do you know what the cons of flash vs twist? You mentioned you wanted to avoid venous contamination, but couldn’t you avoid that by setting the correct temporal resolution or choose only the arterial series in your reconstruction of the twist sequence?

[@Nguyen_MRI]

Good question. With twist you get higher temporal resolution. But standard ce mra you can achieve better spatial resolution.

[@MrLudaGuja]

Have you tried using saturation for MRV/MRA of the neck?

[@Nguyen_MRI]

@@MrLudaGuja yes

[@bassamalameri8804]

your the best always

Bro I need learn how to colour post processing in MRI siemens Vida 3 T perticular part only different colour and add to normal images

[@viresh667]

Thank you so much

[@aamirali4529]

Sir can you please make a video on spinal angiography

[@iansze2652]

Great video Bac......just curious what phase directiom and oversampling you used?

[@Nguyen_MRI]

Thanks. Phase left right and oversaming just enough to avoid fold over.

Chào anh, với những máy không có coil Head-Neck thì nên sử dụng bodycoil hay small coil L để tối ưu khi muốn chụp mạch cảnh - não như bên máy anh?

[@dop887]

Hi Bec, The care bolus sequence in the siemens tree on our scanner is disabled but the test bolus is not. How can I work around it, if I want to use care bolus please?

[@Nguyen_MRI]

What scanner and software are you using? Also this carebolus where did you find it under?
