In Dark Blood Late Gadolinium Enhanced (DB-LGE) imaging, simultaneous signal nulling of the healthy myocardium and the blood and thus yields superior contrast-to-noise ratio of the scared tissues. The method employs a T2-preparation pulse applied after the inversion recovery pulse to rapidly damp the myocardium magnetization relative to the blood. Accurate timing of the inversion pulse, T2-preparation pulse, and echo acquisition is essential for the success of the technique. In this work, we present a simple method for accurately estimating these parameters through fast low-resolution scouting scans played prior to DB-LGE scans.
