Figure 3 Volume Reconstruction of PET-Derived 3-Dimensional Scar Map in Clinical Mapping System

The left ventricle is observed as an ocher-colored reconstruction from basal orientation as indicated by the cardiac icon in the lower left corner. Three-dimensional reconstruction allows the visualization of epicardium but also from endocardium, which can be visualized through the mitral valve plane. Basal, left lateral wall defect is seen as a "hole" in the reconstruction signifying myocardial scar (white arrow, A). A left lateral view allows the visualization of the epicardium with obvious wall defect due to the myocardial scarring described previously (white arrow, B). A right anterior oblique view (B): the "clipping" of the left ventricle allows the visualization of the epicardium and endocardium and demonstrates the corresponding myocardial thickness (En =endocardial surface; Ep = epicardial surface). Myocardial scarring is well visualized as wall defect (white arrow, C). PET = positron emission tomography.
