Core Tip
Core tip: Late gadolinium-enhancement magnetic resonance imaging is the gold standard for imaging myocardial viability, especially for assessing location and extent of myocardial scar in patients with ventricular-tachycardia, which allows for more identification of the ablation targets. However, large percentages of these patients have cardiac-implantable electronic devices, which results in hyperintensity artifacts that obscure the myocardial scar. In this study, we developed a modified technique to alleviate the metal-induced image artifacts without increasing scan time or requiring additional hardware. The developed technique was tested in phantom and in-vivo scans, which showed its capability for suppressing the hyperintensity artifacts and improving diagnostic image quality.
