mri_fit_parms should do it. BTW, if you are using a siemens scanner, you
should just collect an MP2RAGE. That automatically outputs a
quantitative T1 map using the two inversion technique. The results are
much more accurate than using multiple flip angles

Hello,
I am interested in doing some T1-mapping analyses on some ex vivo brains. We
have collected flash sequences under multiple flip angles (5, 10, 15, 20, 25
and 30). How would you suggest that I proceed? Should I use the mri_ms_fitparms
to come up with the T1 maps for each subject and then
sure

Hi Johannes
you should give it a flip angle map in degrees. We assume that the nominal
flip angle (that is, if B1 was homogeneous) would be 60 deg.

Dear all,
For a structural study, I would like to determine cortical T1 values. T1 map
generation from two FLASH images works like a charm, and I would like to add B1
correction now.
I have acquired flip angle maps for my subjects (using the Yarnykh method with
interleaved FLASH and two TRs), a
