Synopsis

3D whole-heart free breathing water/fat non-rigid motion corrected grey-blood PSIR LGE technique has been recently proposed showing good agreement with conventional 2D grey-blood LGE MRI. Due to the relatively long scan time of ~10 minutes, contrast washout may influence scar detection and limit spatial resolution. Here we compare the proposed 3D grey-blood PSIR LGE after slow infusion and bolus injection at high isotropic spatial resolution to evaluate the benefit of the slow infusion injection. Both pipelines were compared to the conventional breath-held 2D grey blood PSIR-LGE imaging technique. Overall higher quality scores were observed in images acquired after slow infusion.
