Cardiac MRI provides important structural and functional information. However routine quantitative analysis of cine MRI is often restricted to left and right ventricular ejection fraction measurements. Functional assessment of left and right atria is frequently not performed. In this abstract, we present an image acquisition and analysis framework for comprehensive evaluation of all cardiac chambers simultaneously, which leverages limited human input to optimize quantitative functional output and allows for evaluating bi-atrial and biventricular interactions simultaneously that may be important in various disease states.
