Notwithstanding the additional advantages and necessities of MRS and imaging genetics studies, a combination of (f)MRI and PET would allow a direct comprehensive assessment of the functioning of individual brain regions, as well as the interplay on the level of the whole brain (see Figure 1 for a schematic comparison of PET and (f)MRI).
MRI Physics: Tissue Contrast in MRI
The signal recovers from M 0 with the same T1 rate, but it has to recover twice as far to get to +M 0, hence the factor of 2:. Signal recovery after TI = M 0 + eTI/T1 * (M 0 M 0) = M 0 * (1 2 * eTI/T1). Then the 90 degree pulse is applied, moving all of the signal into the xyplane. Whatever we had was lost, so T1 recovery happens just like with a normal spin echo sequence, but we only ...
