Is Gado listed as a contrast agent or a medicine under the FDA? Is it legal for an mri technologist to inject gado? I know we can inject contrast agents but is gado listed under the FDA as a contrast agent or is it listed as something else?

| T1 FAT SAT PRE AND POS GADO |
The contrast agent causes this difference. Contrast agents reduce the T1 time in tissues where they have accumulated depending on blood flow and vascular permeability. Caused by this, tissues after an application of contrast agents will differ in shortening of the T1 time, and the same imaging parameters result in other image appearance.
Some helpful links for musculoskeletal imaging and Fat Sat:

I do not doubt that there are small and may be in special cases (perfusion, MRA, etc.) useful differences.
However, I have a lot of practice in MRI and in my opinion, you are right, the differences are small and you can run every type of MRI scans with all conventional Gadolinium containing contrast agents.

I was told by the GE rep that Omniscan has a faster distribution rate, that should lend itself to better images/application to specific technologies. Is this claim valid? This is the first I've heard of this type "spin" on contrast agents. <pun intended>
In my experience, I have not seen much difference in image quality from various contrast agents. Any thoughts or experiences are appreciated.

| CE-MRA Vasovist protocol |
We will start soon with Vasovist (MS-325) for peripheral CE-MRA with moving table. Expecting higher resolution due to longer possible scan times - but discussing timing and needed post processing.
Is bolus timing needed - is fluoroscopic triggering possible - for the arterial phase?
Any experiences with this contrast agent, a good scan protocol or some good sources about Vasovist?
Anything appreciated!
Greetings
