Motion-corrected 3D whole-heart water-fat high-resolution late gadolinium enhancement cardiovascular magnetic resonance imaging

摘要

3D dual-echo late gadolinium enhancement (LGE) imaging acquisition framework. Low-resolution 2D image-based navigator (iNAVs) are acquired before 3D dual-echo undersampled data acquisition for motion estimation, while inversion recovery (IR) preparation pulses are used to null the viable myocardium signal. The trigger delay and acquisition window are set to coincide with ventricular mid-diastole
