Non gated real-time cardiac MR imaging with Partial Separable model provides a promising way to overcome the limitation of conventional cine imaging. The new method is able to capture the beat by beat variation, which is especially suitable for arrhythmia. In this study, we have 2 aims. First, to evaluate the consistency of parameters between the conventional cine method and the PS model based real-time method, and second, to capture beat by beat variation in arrhythmia patient.
