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?
