Respiratory self-navigation (SN) for whole-heart MRI provides 100% scan efficiency and increased ease of use for the operator. The SN technique was combined with a 3D radial acquisition for phase sensitive inversion recovery (3D-SN PSIR) imaging, featuring high motion and undersampling robustness. Free-breathing 3D-SN PSIR was compared to standard 2D breathhold PSIR imaging in patients with positive late gadolinium enhancement findings. Preliminary results show that free-breathing 3D-SN PSIR achieves robust nulling of healthy myocardium, while preserving high-signal in fibrotic tissue. Overall high diagnostic quality is preserved. Such high-resolution isotropic scar definition could allow for better planning of arrhythmia ablation procedures.
