Current techniques do not allow simultaneous acquisition of velocity and T1 data in a rapid breath-hold scan for renal imaging. This study offers an approach that solves this and reveals a trend that relates T1 to velocity. An inversion recovery EPI scan was modified to enable phase-contrast velocity encoding. Results from a phantom experiment reveal that T1 and velocity data can be acquired simultaneously, and that velocity is only reliable in the plateau periods of the signal curves. These findings show promise for the use of the technique in clinical settings.
