Figure 1: CTPA parameters. A: Pulmonary artery (PA) and ascending aorta (AA) ratio (PA/AAAX) on an axial view at the level of the bifurcation of the pulmonary trunk. B: Right ventricle (RV) and left ventricle (LV) ratio (RV/LVAX) on an axial view. The RV diameter is measured perpendicular to the long axis of the heart. The LV diameter is not measured in this image, since the maximum diameter of the LV is not necessarily on the same image. C: RV/LV4CH on a four chamber (4CH) view.
