The objective of this study was to assess correlation
between cardiac functional parameters and some types of
myocardial T1 values and extracellular volume fraction (ECV),
given by MOLLI, in dilated cardiomyopathy (DCM).
Myocardial T1 value before contrast showed good
correlations with several cardiac functional parameters.
ECV derived from 10 minutes after contrast also showed
good correlations. The interventricular septum was the
appropriate region for assessing the T1 and ECV related
to cardiac functional parameters in DCM.
