Aortic measurements at multiple levels. 3D bSSFP image, reconstructed into the long axis of the aortic arch (A). Lines display recommended locations for measurement: ascending aorta, distal transverse aortic arch, aortic isthmus and descending aorta at the diaphragm. Double oblique images should be reconstructed at each of these levels (B-ascending aorta) for en face measurements
