You definitely have to have multiple echo measurements.
I'd encourage you to do a proper literature search on T2* measurements in pubmed.
Good luck,

Hi all,
There was a fMRI dataset acquired from real MRI machine. Can I calculate
T2star from it? For example, using relaxometry[S(t) = S(0)exp(-t/T2)]. But I
don't know S(0).
Thanks.
Zheng
