A real-time LGE MRI technique (free breathing, non-gated) is presented for detection of myocardial scars. Conventional real-time LGE imaging has long acquisition window and low temporal resolution. The goal of this study was to increase the temporal resolution of imaging, providing the possibility for better visualization of the wall motion and more accurate assessment of myocardial viability. The number of acquired images is more than twice the number in previously published methods. 12 single-shot images were acquired using an IR TFE-EPI sequence in a single heat beat. Unlike other methods, ed-myocardium is acquired without the need to set TI value.
