Conventional first-pass myocardial perfusion MRI methods
are prone to dark-rim artifacts. We developed a
free-breathing DRA-reduced FPP scheme with Cartesian
k-space sampling and instantaneous online image
reconstruction. This can be implemented into clinical
routine, enhancing its clinical accessibility.
Preliminary results of canine with myocardial infarction
showed high accuracy compared to late gadolinium
enhancement imaging.
