Magnetization prepared segmented acquisition requires a view order that maximizes signal contrast during the acquisition of the central portion of k ‐space. Steady state free precession (SSFP) acquisition further requires a view order that minimizes changes in phase‐encoding gradients from one repetition to the next in order to minimize eddy current artifacts. In this article, optimal view ordering schemes satisfying these two requirements are formulated and applied to inversion prepared 3D SSFP contrast‐enhanced MR angiography (MRA). Experiments on phantoms and pigs demonstrated improved background suppression and reduced image artifacts. Magn Reson Med 52:461–466, 2004. © 2004 Wiley‐Liss, Inc.
