A new real-time cardiac MRI technique combining the advantages of spiral imaging with flexible golden-ratio acquisition ordering and acceleration from self-consistent parallel imaging is presented in this work. The scan acceleration achieved by the proposed technique is used to acquire free-breathing real-time images at a relatively high in-plane resolution of 1.6 mm and expanded field of view of 40 cm. Adequate temporal resolution is maintained to visualize cardiac and respiratory motion.
