Greetings,
It depends on what exactly what you mean by T2* mapping?
If you are referring to determining the time constant then the same post
processing plugin will work. 1/T2* = 1/T2 + 1/T2'; A spin echo pulse
sequence eliminates, i.e, reduces to negligible level, the T2' component
leaving just the T2 component. A gradient echo sequence includes the T2'
component.
If you are referring to creating deltaB0 map, then you need to do a linear
fit to the phase image, albeit with special handling of the phase wrap. I
have a plugin for this. (I have not yet dressed the code up for release
though)
If you are referring to Susceptibility Weighted Imaging, I do not know of
a ImageJ plugin, albeit there are other tools out there.
Enjoy,
Fred
