I have same trouble with counting T1 of the gadolinium solution.
f.ex.
There are six fantom with gadolinium solution in 0.5, 1, 2, 4, 8 and 16 mmol/l. Fantoms scanned with pulse sequences SE with TR equal 50, 100, 200, 300, 400 ... 4000 ms. For each fantom calculated T1 by iteractive minimizing technique the equation: S(TR)=M0*(1-exp(-TR/T1))
At the result, I have six T1: 72, 170, 255, 403, 725, 1474 ms.
How can I calculate T1 and R1 of the pure solution of contrast media?

Hi, I'm a new transcriptionist looking for help on a captopril renal scan. Dictator says something that sounds like "a renal scan was performed 1 hour later after 10.3 (millicreets) of (garbled poss MAG3. Any help would be appreciated ASAP. Thank You

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?

Why you didn't see toshiba, they have speeder so you can reduce scan timing, and they have T-slip and FBI
technique, you can see artery and vein without contrast injection even in peripheral artery. I already saw and try that technique at toshiba factory, japan.

I dont see any reason ,why one should have problem with large FOV Proton Density images, technically i dont think there is any such restriction.
what is the exact problem you facing with large FOV PD images?
