Phase contrast MRI (PCMRI) provides flow information similar to 2D echocardiography without the restrictions of acoustic windows. High temporal resolution PCMRI may prove to be very useful for evaluating valvular dynamics, and for studying flow patterns in the cardiac chambers. A new approach utilizing dual echoes and parallel imaging is presented for obtaining high temporal resolution flow information in a breathhold examination. The results obtained in flow phantoms and humans compare well with flow results obtained using conventional FLASH-based phase-contrast sequences.
