This study demonstrated that phase-sensitive inversion-recovery technique was feasible for free-breathing 3D delayed-enhancement MRI at 3.0T, because it significantly improved the confidence for the presence of the hyperenhancing myocardium and the image contrast between the myocardium and blood. However, the 3D MRI without PSIR could not be omitted in some patients, because of its fewer image artifacts and no deterioration of the image quality.
