| vibe sequences in neuro mri? |
I am trying to cut down on time and have read a few articles that talk about mprage and vibe imaging but I am wondering if I can use them for post contrast imaging instead of t 1 sequence on my brain and spine studies. Anyone have any experience or comments about that?

Thomas,
Regarding room specs, if you are buying new equipment the manufacturer will provide all of this to you at no additional charge.
If you are considering preowned systems it is a little more difficult. You would need to find a company that specializes in the particular type of open system that you are considering. A word of caution would be that most people will tell you that they know the systems inside and out. Be careful and check the credentials of the service provider and ensure that they do in fact know the system you are considering. Also it is always a good idea to talk with some of their clients to get feedback on work that the company has performed.
If you are considering a Hitachi Open MRI, my company can help you out. We are in fact experts on these systems. If you want to talk about your project visit our website at viablemed.net and use our contact page to reach us.
Good Luck,
Dan McGuan
