2. Fig 1
The dilated main pulmonary artery (MPA) is seen with aliasing of the Doppler color flow caused by an increased velocity of flow across the pulmonary annulus. The ventricular septal defect (VSD) is also seen. (RV = right ventricle.)

3. Fig 2
Early and late arterial phase images from a left ventriculogram. (A) Early phase demonstrates the ascending aorta bifurcating into right and left common carotid arteries. (B) Late phase demonstrates opacification of the vertebral and proximal subclavian arteries, which join to supply the descending thoracic aorta.

4. Fig 3
Gated spin-echo magnetic resonance images. (A) Dilated pulmonary artery (PA) communicating with the descending thoracic aorta (Ao) via a minute patent ductus arteriosus (PDA). Bifurcation of the descending thoracic aorta into left and retroesophageal right subclavian arteries can be seen. (B) Transverse image just below the skull base demonstrating large, tortuous collaterals between the internal carotid arteries and the vertebral arteries. (LIC = left internal carotid artery; LSA = left subclavian artery; LVA = left vertebral artery; RIC = right internal carotid artery; RSA = right subclavian artery; RVA = right vertebral artery.)
