Three-dimensional rotational myelography.

Three-dimensional (3D) rotational radiography, initially developed to visualize intracranial aneurysms, is applied to the cervical spine after conventional myelography. We call this process 3D rotational myelography. 3D reconstruction and then postprocessing allows imaging in multiple planes. Spinal or nerve root sheath alterations caused by bony or soft tissue can be visualized and differentiated by using this technique.
