Detection of great arteries alignment in TGA and normal fetuses using 4D volumes with color flow information. In a 24-gestational-week fetus with TGA (a), parallel great arteries were clearly identified by the 4D rendered image. The pulmonary artery was originated from the left ventricle while the right ventricle gave off the aorta. In a normal fetus (b) of similar gestational age, the 4D rendered image demonstrated that the two great arteries were orthogonal to each other originating from each ventricle. AO, aorta; LV, left ventricle; PA, pulmonary artery; RV, right ventricle; TGA, transposition of the great arteries
