We aimed to investigate the role of motion-corrected phase-sensitive inversion recovery (MOCO-PSIR) technology for the evaluation of LGE. LGE imaging was conducted in 55 patients with MOCO-PSIR and conventional breath-hold PSIR sequences ā€ˇsuccessively. Image quality was scored using a four-point scale. Compared with conventional PSIR, MOCO-PSIR showed better image quality and detected larger LGE volumes in nonischemic cardiomyopathy. Free-breathing motion-corrected PSIR method is a promising alternative to conventional PSIR sequence.
