| MRV--Phase contrast question |
What exactly is an MRV sequence on an Hitachi Airis II .3 Tesla?
I realize it has to do with the venus system but if anyone knows anything I sure would appreciate your time and knowledge concerning this.
Also The physician I am working under(Neurologist), he would like to see my MRAs done with a phase encoding protocall? Is there such a thing? I hope someone out there can give me some knowledgable info on this. Thank you Sheila/Georgia :)

I do not doubt that there are small and may be in special cases (perfusion, MRA, etc.) useful differences.
However, I have a lot of practice in MRI and in my opinion, you are right, the differences are small and you can run every type of MRI scans with all conventional Gadolinium containing contrast agents.

ITS REALLY NOT NECESSARY TO ROUTINELY DO CE MRA OF THE "COW". BY UTILIZING A 3D SPOILED FAST GRE THEN MANUALLY RECONSTRUCTING THE MIP THE ARTERIES ARE SUFFICIENTLY ENHANCED.

Hi,
seems crazy, you should have many undesirable veins! We run a 3D TOF MRA of the circle of willis without contrast with best results (1.5T and 3T).
Contrast enhanced 3D MRA of the carotids are done with machine injection (never with a butterfly!), automated bolus detection and a flow of 3ml/sec and 25 ml Gad. If no bolus detection program is available, look for the delay with a test bolus of 2ml. With a high resolution scan, both carotids and circle of willis are assessable. The use of a set like Smartset for the injection is helpful if no power injector is available.

Like lily lily we use a muliphase MRA with 3 phases (artery, portal vein and late phase).
We use an amount of 30 ml Gadolinium with an injection rate of 5 ml/sec. With this high flow rate, you get a more concentrated bolus and therefore a higher contrast for the second phase. We use CENTRA k-space acquisition and reduce the scan time with SENSE (a parallel imaging technique like ASSET ), this will help for a better timing.
