In this work, we obtained phase sensitive inversion recovery (PSIR) signal from MPRAGE and MP2RAGE sequences. Both PSIR images have better image contrast than magnitude images. The PSIR from MPRAGE requires shorter acquisition time, however, PSIR from MP2RAGE provides better contrast and has no $$$B_1$$$ field inhomogeneity effect. Selection of which PSIR technique to use may depend on study aims.
