Dynamic quantification of myocardial T
1
pre-
and post-injection is a useful tool to evaluate
fibrosis. These quantifications require numerous
acquisitions and are therefore very sensible to inter-
and intra-acquisition motion, especially in patients who
can barely hold their breath. Here, we propose a motion
compensation method that can be applied on
multi-contrast acquisitions by taking advantage of
redundant information. This motion correction was
applied on data sets acquired in free-breathing in two
patients with Duchenne Muscular Dystrophy. The proposed
method was shown to improve the differentiation between
regions of the myocardium with different stages of
fibrosis.
