Achieving sufficiently good quality co-registration
between the anatomical and functional images is currently a large stumbling
block for laminar fMRI. Here, we present a distortion-matched T1weighted/T1-estimation
mapping approach using two 3D-EPI readouts per inversion, following the MP2RAGE
signal combination. 0.7mm isotropic T1 data with matching
distortions to a 0.7mm isotropic fMRI protocol can be acquired in less than two
minutes.
