T
2
*
mapping
is an emerging technique holding the promise to provide
advancement in myocardial tissue characterization. The
linear relationship between magnetic field strength and
microscopic susceptibility renders it conceptually
appealing to pursue myocardial T

mapping
at ultrahigh fields. Gradient echo based techniques show
pronounced propensity to susceptibility artifacts due to
the required long echo times. This work investigates the
feasibility of RARE based T

mapping
at 7 T using bowtie antennas to offset RF power
deposition and RF non-uniformity constraints. Myocardial
T
2

mapping
at 7 T is feasible and provides susceptibility weighted
images and T

maps free of
distortion.
