Example images of 3D IR bSSFP imaging using pencil beam navigation. As can be seen in all three panels, these proved to be unusable because the navigator labeled the blood in the liver and thus the overall image quality was degraded. This is perhaps due to the high signal in the liver causing an overall compression of the dynamic range. a Image from a patient with d-transposition of the great arteries, ventricular septal defect (VSD), and pulmonary stenosis status post aortic root translocation and VSD closure. b Image from a patient with a large secundum atrial septal defect. c Image from a patient with trisomy 21 and common AV canal status post surgical repair
