The
sensitivity and specificity needed to detect neuronal activation is affected
by the type of fMRI sequence and reconstruction algorithm used. Recent development of a new single-scan
imaging scheme provides an alternative fMRI tool, based on spatial encoding,
which offers higher robustness to B0 field inhomogeneities. A new post-processing procedure was
combined onto this scheme based on super-resolution image reconstruction
algorithms, which improves the ensuing spatial-resolution while reducing the
initially higher hardware requirements and SAR constraints. We analyze the performance afforded by
super-resolution using two novel spatially-encoded based sequences for human
fMRI studies, as compared to standard EPI.
