| How to setup a MRI room? + questions |
I'm planning to purchase a used 1.0-1.5T MRI and I had a few questions.
From what I gather, I need a 480V line, correct? The unit 1.5T takes about 150amps. Does it suck all that power 24x7, or when it's on? If not all the time then how much when it's on standby?
What kind of cooling would I need? From what I read a helium? gas setup? What about A/C? how strong would I need?
What about the room. What size does it have to be? does it need any special insulation?
And are there any companies in Europe what can design and build a room for it?

Hello, Hitachi just came out with a PVA coil last month. I haven't seen pictures from it, but hear they look good, with or without contrast.
We just had an Echelon 16 channel installed 3 weeks ago, Protocols right out of the system box look good, still have some tweaking to do.
Any suggestions on protocols are GREATLY APPRECIAED.
Thanks, Keith

| Feridex/endorem and bone MRI |
I would like to label cells with a paramagnetic particle to see it in vivo by MRI after implantation inside a bone defect.
I am thinking on feridex/endoderm, it has contrast effect T2, predominantly negative enhacement.
Does anybody know something about this?
Will I be able to see this kind of signal by MRI? White or blak?
Thanks a lot.

| PCA aliasing problem |
This is not spatial aliasing I am talking about, but velocity aliasing. This means that when your velocity encoding parameter is set to 100 cm/s and true velocity in a certain pixel is 120 cm/s, the measured velocity will be -80 cm/s.
In my problem however, with a velocity encoding parameter of 100 cm/s, in certain pixels I measure a velocity of around -60 cm/s where an actual velocity of 40 cm/s exists, which is a real mystery to me.
I don't think increasing FOV will prevent this from happening. Maybe it has something to do with velocity aliasing in other parts of the FOV, where true flow velocity of 110-120 cm/s exists, but I wouldn't know why. Anyone? Thanks.

what are the optimal relations between the various parameters of a FLAIR?
I noticed that the TR is almost 4 times the TI. Why?
there are arrangements to be considered on TE?
thanks
