The benefits of the current cardiac CINE MRI are often limited by the requirement of patient co-operation for multiple breath-holds. To overcome this limitation, we present a new, free-breathing respiratory motion-compensated 2D multi-slice radial CINE method for left ventricular functional assessment. Our method utilizes the respiratory signal obtained from a patient sensing camera for performing motion weighted density compensation in radial gridding to minimize respiratory motion artifacts in the reconstructed image. The left-ventricular functional assessments from volunteers obtained using the proposed method are in good agreement with the results obtained using the standard Cartesian breath-hold method.
