Comparison of four short axis cine acquisition protocols for the evaluation of left ventricular cardiac function

Background Guidelines from the SCMR board try to standardize the acquisition and post processing protocols for uniform and reproducible analysis of cardiac data. However, for short axis cine acquisition, the definition of the image orientation for data acquisition is not well defined, possibly leading to variation in the evaluation of the Left Ventricular cardiac function. Having a standard definition is particularly important for multi-center and longitudinal studies. Very little work has been done to evaluate the impact of the various proposed protocols on measurement results of Left Ventricular function, which is the aim of this study.
