We also calculated two specific indicators for the vertebral body / intervertebral disk assembly, namely: the relative disk-vertebral index and the disk-vertebral angle index.
We consider that the values we obtained are more reliable in reference to dimensional ratios between the vertebral-disk elements than the ones obtained by the old formula, namely the direct ratio of the intervertebral disk height and the corresponding vertebral body height.

Other notochordal lesions include notochordal vestiges of the intervertebral disk and ecchordosis physaliphora (EP).
