Figure 20:

Extracardiac Fontan procedure biphasic acquisition protocol. (A) Coronal reformatted maximum intensity projection (MIP) CT image in the early arterial phase shows well-opacified aortic root. The Fontan circuit is not opacified, giving false impression of thrombosis. (B) Coronal reformatted MIP CT image in the late venous phase shows uniform opacification of the Fontan conduit. Ao = aorta, C = conduit, LPA = left pulmonary artery, RPA = right pulmonary artery, SVC = superior vena cava.
