yes of course i like it thank you again !

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

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

masha allah you are the best

Thank for the vedio. Great content

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.

thank you very much,very useful

your the best always

Thank you very much Very useful knowledge

Thank you so much

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.

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.

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

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?

Sir can you please make a video on spinal angiography

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

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?

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?
