A scout-less imaging method for step-table whole-body contrast-enhanced magnetic resonance angiography is described. This method uses non-selective RF excitation for rapid data acquisition using predetermined settings for the 3D volumes and table-shifts. Because the data are acquired through the total thickness of the body, there is no need for acquisition of multiple scout images and manual positioning of the multiple imaging volumes. The entire four-station study, including mask and angiogram images, can be completed in seven minutes or less.
