Question

Hi,
Excuse me, can you help me to solve?
The normal human brain at 3 T has tissue T1 and T2 times. Which of the following shows the correct tissue-longitudinal magnetization pair after 30∘ flip angle and 400 ms time delay if the initial magnetization M0=1? (At 3 T, T1 and T2 values of gray matter are 1331ms and 80ms respectively. T1 and T2 values of white matter are 832ms and 110ms)
Gray Matter, Mz=0.55
White Matter, Mz=0.36
White Matter, Mz=0.74
Gray Matter, Mz=0.90
