Recent
advances in coil technology have enabled cardiac imaging to be performed at
7T, with high spatial resolution cine-imaging showing particular promise. However,
there has been no quantitative assessment of clinically-relevant derived
measures of cardiac mass, volume or function. In this current study, ten
healthy volunteers underwent cardiac scans at both 1.5T, the gold standard
for such measures, and 7T. Values of end-systolic and end-diastolic volumes,
ejection fraction, stroke volume an left ventricular end diastolic mass
showed no statistical difference between 1.5 and 7T, providing strong
validation for the continuing development of high-field cardiac imaging.
