Figure 1

LA volume reconstruction using a sCINE-IR acquisition. Left : sCINE-IR acquisitions through the LA. Images a and b correspond to SAX and images c,d and e to SAX. Middle : the 3D-reconstructed LA volumes (red casts) are shown at 5 different time points during the cardiac cycle, oriented perpendicular to the mitral valve to illustrate the mitral valve motion and lengthening and shortining of the LA long axis. Right : figure at the top illustrates the 5 contours at time point 4, used to reconstruct the LA volume at time point 4 (center right). At lower right, the LA volume curve is given over the entire cardiac cycle (I=LA passive emptying volume; II=LA active emptying volume; III=LA total reservoir volume)
