We present initial results of our novel full chest, free-breathing 4D-flow protocol which was designed for clinical use. In 25 patient who required imaging of aortic and pulmonic flow, it proved to be feasible for two reasons: mean acquisition times of 4D-flow was 12.5min versus 9.7min for 2D phase contrast (2D-PC) imaging, resulting in only a minor mean measurement time increase of about three minutes. Second, flow measurements for aortic and pulmonic flow for were consistent for both 4D-flow and 2D-PC. We will continue with our evaluation in a larger cohort to confirm these initial results.
