To
demonstrate that assessment of cardiac iron burden by T2* imaging is feasible, reproducible,
and reliable at 3T. With 3T MRI scanners increasingly used in clinical
settings, this study may lay a foundation for further MRI development of
quantitative markers for noninvasive cardiac iron overloaded assessment at
higher fields. Though cardiac T2* measurement at 3T seemed not to offer any greater
advantages than 1.5T at present, it is more useful for some hospitals having
only 3T scanner.
