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.
