Late Gd enhancement imaging is a well-established tool
for the determination of infarcted myocardial tissue.
However, the necessity for the operator to manually
adjust the effective inversion time TI prior to a LGE
acquisition makes the acquisition susceptible to
sub-optimal contrast between vital and necrotic tissue.
The aim of this study was to incorporate a
forward-backward motion correction in the model based
acceleration of parameter mapping (MAP) technique to
reconstruct images of multiple contrasts out of a 2D
dataset acquired after a single IR preparation. The
presented method allows for retrospectively selecting
the desired image contrast and thus improves the
flexibility of diagnostic LGE imaging.
