High resolution T2-weighted dark blood (HR-T2W-DB) imaging is not always robust for clinical use because of low SNR and long scan time. The purpose of this study was to evaluate a novel deep learning (DL) based reconstruction method in T2W-DB sequence that achieves higher spatial resolution and same scan duration compared with traditional reconstruction method. Quantitative and qualitative image assessment demonstrated that DL based HR-T2W-DB sequence showed better CNR in region of edema and LV free wall visibility, which might help detecting myocardial edema.
