Cine bSSFP is routinely used to image left ventricular structure and function. Changes in signal intensity of images throughout the cardiac cycle are affected by changes in tissue composition and longitudinal shortening. We found that reduced longitudinal ventricular shortening and reduced peak changes in bSSFP signal intensity could be used to differentiate healthy patients from those with LGE enhancement.
