A gadolinium-type contrast will be used, which is chemically different from the iodine-based contrast agents used for IVPs, CT scans and angiograms.
A lot of ppl say it feels "cold" going into the vein.
You can do a search using the words "MRI contrast liver" and come up with many articles. Perhaps "gadolinium MRI liver" would give you some hits more specific to your question.
I copied one link (below) about a potentially serious adverse effect of receiving gadolinium, which doesn't apply to everyone. http://www.sciam.com/article.cfm?ali...rc=reuters_box
Are you claustrophobic?
Some ppl don't realize the scanner may give them a claustrophobic feeling ("I've never been claustrophobic, I don't know why that tube bothers me!").
Some ppl require a dose of (po) medication (Ativan, Valium, etc) 30-45 min before the scan, for their claustrophobia.
Some ppl can go thru with a towel over their eyes.
Other ppl have told me, "DON'T put anything on my face!"
I have to close my eyes before being moved into the scanner, and if I keep them closed the whole time I'm in it, I'm OK.
I hope your test goes well, and the results are helpful. --- D
Edited: I just re-read your post. Perhaps you should phone the Imaging Center where you'll have the MRI and ask what the contrast agent's name is, as the gado we used to give was given slowly IV (causes N/V in some ppl if given too fast), and then the pt was immediately returned to the scanner to finish the exam. No waiting 2 hr. So, the contrast may be different, and the Imaging Center should be able to fill you in w/details (or at least give you the name so you can google it. )
