| 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 :)

| interleaved slices and mean intensity difference in adjacent slices |
With interleaved slice acquisition for example in each TR first the odd slices, and then the even slices are acquired. Differences in signal intensity may occur by changes between these acquisitions (like movement), especially with a long TR. In particular, for fMRI sequences with interleaved slice acquisition a slice time correction is recommended to get accurate measurements.
However, I think "large" signal intensity differences with interleaved slices (except fMRI) are rarely seen with usual sequences and sufficient processing (interpolation) algorithms.

Hello!
Is my first time in this forum! I read it a lot this forum, is very helpfull for my job!
I have a dificult in my mri machine.
First i would like to now how can i construct a bolus teste manualy! I don't have smart prep. What sequence i must use and what parameters i must choose.
Second, can you expline to me the diference between centric fill of K-space and non centric?
When is the best time to star the sequence after take the time injection.
My regards
Marco Costa

Can anyone please give directions for how to use the SpectroScan Tool in spectroscopic sequences.
It is necessary to optimise the shimming in spectroscopy in order to get well defined sharp peaks in the metabolites spectrum.

Thank You,
Please excuse me But how should the silicon scout look?
What other sequences should I run to complete the protocol, and will the other sequences be affected by the scanner tunning to silicone instead of water?
