Ureteral peristaltic wave frequency and velocity are imaged non-invasively 20 minutes post-gadoxetate disodium injection when there is maximal ureter to tissue contrast. A spiral 3D reconstructed at 4 frames per second from 60 seconds of data captures peristalsis adequately to resolve wave peaks for frequency and velocity calculations.
