title: Motion of the proximal renal artery during the cardiac cycle.
abstract: In 48 hypertensive patients, the motion of the proximal renal artery during the cardiac cycle was quantified using two-dimensional quantitative flow (QF) measurements and automatic contour detection. Substantial translational motion was observed with an amplitude ranging from 1 to 4 mm. Since motion effectively reduces spatial resolution, the use of motion suppression techniques should be strongly considered for renal MR angiography. J. Magn. Reson. Imaging 2000;12:924-928.
