A data analysis framework is proposed to study the
relation between scar severity and regional myocardial function during the
process of remodeling after acute myocardial infarction (MI). The framework
includes registration steps to correct for slice-to-slice inconsistencies, to
align cine with late gadolinium enhancement (LGE) data and to align data from
follow-up scans. The framework was evaluated in 114 patients with CMR scans
within 3 days after MI and at 6 months. Registration accuracy was below 3 mm.
Results show that function at 6 months was inversely associated with scar transmuraltiy
at both 3 days and 6 months.
