Free-breathing cine DENSE MRI using phase cycling with matchmaking and stimulated-echo image-based navigators

摘要

PurposeThis study aimed to develop a self-navigated method for free-breathing spiral cine displacement-encoding with stimulated echoes (DENSE), a myocardial strain imaging technique that uses phase-cycling for artifact suppression. The method needed to address two consequences of motion for DENSE: striping artifacts from incomplete suppression of the T1-relaxation echo and blurring.
