| Imaging of the sacral plexus |
We are students Technical Medicine from Twente University and are researching the imaging of the anatomical variation of the sacral plexus. This means the imaging of nerves in a fatty/muscle enviroment with a diameter below 1 mm.rnrnWe are interested in different MR-sequences that will show these small nerves (at the moment we came up with MP(2)Rage, STIR, normal SE T1 and DW) Does anybody can provide us why we should or shouldn't use one of these sequences. Or maybe somebody does have a better suggestion?rnrnAlso we were planning to combine spinal and abdominal coils (phased-array RF coils), does this depict the sacral plexus in a good way?rnrnWe also thought about using a 7T MRI scanner, because of the high spatial resolution. Is this a possibility or does it give to much artifacts? Or is the spatial resolution in a 3T machine enough for such small nerves?rnrnThanks in advance!

| MRI registry equations |
now i'm disappointed i failed modules 4-5-6-7-8. 4-5-6 i thought i was good with my wife told me my scores so when i see it i hope all the ones i got wrong were all those stupid "filler questions" (b/c they are good for credits)that questions that i got wrong.
example: what happens when the service engineer mistakenly connects the z gradient coil to y gradient amplifer, and the y gradient coil to the z amplifer or something like that the registry don't ask that from what i was told
now i know why my friend took a live taught course cause he had mic and liked it then hated it

| GE LX MRI Platform? |
LX platform was starting 1997; upgrade from 5x to LX (9.1) is the whole hardware except Magnet and table, LX was the last platform for 1.oT systems. All 1.5T and 3.0T system can be upgraded to 15x ( HDxT) platform but all magnets before LCC Magnet( starting 1998) have the limitation max. 8 channels. The upgrades from 11x to 15x have new computers plus parts of gradient cabinet and system cabinet and coils. For the new 750/450 platform it is more difficult to upgrade, kompl. new hardware.

| dedicated vascular coil |
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

| Which MRI machine to buy? |
Hi Mike,
Is this your first MRI scanner purchase? I would recommend GE over Hitachi because it is more universal and it will be easier (and less expensive) to get service and refurbished parts. When you say high field do you mean 3.0? Since those are so costly, a 1.5T will give you the best value. That's what we currently use and with the right coils we obtain high quality images.
Hope that helps,
Sandra
