Accurately acquiring the location and extent of thin atrial fibrosis patterns demands for improved imaging techniques compared to conventional ventricular LGE. Recently, we developed a novel 2D dark-blood LGE approach that significantly increases scar-to-blood contrast without using additional magnetization preparation. In this feasibility study, we sought to translate this novel approach towards 3D fibrosis imaging for simultaneous detection of both atrial and ventricular scar. 3D dark-blood PSIR LGE proves to be a readily available approach for detection of both atrial and ventricular fibrosis, with improved robustness for arrhythmias, increased scar-to-blood contrast, improved patient comfort, and enabling a more versatile analysis.
