The purpose of this study is to eliminate low and dark flow artifact at descending aorta encountered at 3.0T on 3D Balanced Steady State Free Precession (bSSFP) with slab selective inversion pulse for visualizing renal arteries.@A novel trigger procedure is presented with triple triggers for achieving both carotid and respiratory synchronized data acquisition despite the use of long inversion pulse over 1 second. The comparison study was performed to conventional respiratory trigger alone sequence on 1.5T and 3.0T. Compared to the conventional respiratory trigger the advantage of the proposed approach is robust, uniform and high arterial blood visualization.
