Figures
Long- and short-axis images through the interatrial septum show a small patent foramen ovale (arrows) with the jet of contrast from the left atrium (LA) to the right atrium (RA). The right heart is less dense due to washout of contrast by saline chaser. Cardiac images are obtained on the basis of relative timing intervals in steps of 10% of the R-R interval in cardiac cycle. The centre of reconstruction is placed at the relative point as shown in the diagram (top right). On the left side, high-resolution long- and short-axis views are reformatted from diastolic datasets centred at 70% of the R-R interval, with a slice thickness of 0.5 mm and increments of 0.3 mm. On the right, short-axis cine frames (2 mm thickness) from collected data at 10%, 30%, 60% and 90% intervals are shown.
