Tomographic Ultrasound Imaging in a fetus with transposition of the great arteries. A) B-mode imaging. (1) In the three-vessel and trachea view, only the aorta is visualized, leaving the right ventricle; (2) the five chamber view demonstrates a vessel that bifurcates (pulmonary artery) connected to the left ventricle; (3) the four-chamber view is normal. B) Color Doppler imaging. (1) the three vessel view shows the aorta connecting to the right ventricle; (2) the pulmonary artery leaves the left ventricle and bifurcates. Legends: PA = pulmonary artery; Ao = aorta; RV = right ventricle; LV = left ventricle; 3V = three vessel; 3VT = three-vessel and trachea; SVC = superior vena cava; 4CH = four-chamber; 5CH = five-chamber; Trv = transverse
