We develop a new free-breathing technique for myocardial
T2* mapping using single-shot gradient-echo echo-planar
imaging (GRE-EPI) coupled with automatic non-rigid
motion correction. We test our method in T2* phantoms
and six healthy volunteers. In both phantom and
volunteer studies, no significant difference was
observed between the T2* measured using our proposed
method and the T2* measured using the standard
ECG-triggered segmented black-blood multi-echo gradient
echo (mGRE) sequence. Our approach provides accurate
myocardial T2* measurements during free-breathing and is
insensitive to respiratory motion.
