Figure 2

Volume rendered MSCT images from two cardiac phases (35% and 95% corresponding PV maximal and minimal volumes). The images are viewed from a posterosuperior angle and the location of all four pulmonary veins is marked in the upper panel. In the lower panel, atrial contraction is visible and there is significant contraction in left superior pulmonary with a lesser degree of contraction of the right superior pulmonary vein. The inferior pulmonary veins appear to be the same volume between the two phases in this case.
