Large field of view CE MRA using parallel imaging. Parallel imaging and a 32-channel coil were used to scan the entire aorta from the aortic root to beyond the bifurcation in this 49 year-old male with prior ascending aortic dissection repair (arrowheads) and residual dissection in the descending aorta (open arrows = true lumen; closed arrows = partially thrombosed false lumen).
