How can measure overriding of aorta in ct angio?

To measure the overriding of the aorta in CT angiography, you can assess the spatial relationship between the aorta and the ventricles, particularly the right ventricle and left ventricle. This is typically done by evaluating the aortic root's position relative to the ventricular septum and the origin of the pulmonary artery. The angle of the aorta, its location above the septum, and the presence of any accompanying anomalies can also be quantified. Measurements can be taken directly from axial slices or reconstructed images using appropriate software tools.
