A recent proposed technique called four dimensional, multiphase, steady-state imaging with contrast enhancement (MUSIC) enables detailed anatomical assessment of cardiovascular system. However, limited available cardiac phase prevents accurate functional assessment of the heart. In this study, we compared original MUSIC with an improved MUSIC technique that generates double cardiac phases. Initial results suggest a more accurate left ventricular volume measurement and better appreciation of cardiac wall motion can be achieved with more cardiac phases.
