Background
Degenerative discogenic diseases of the vertebral column are mainly caused by malformation or dislocation of the intervertebral discs and deformations of the spinal cord. Slipped or ruptured disks can cause severe spinal stenosis, narrowing of the spinal canal and a resulting constriction of the nerves. In the same context the term spondylolisthesis refers to a forward displacement of a lumbar vertebra on the sacrum which again produces a compression of nerve roots. For the diagnosis and the therapy planning of intervertebral disk diseases detailed information of the relevant structures and their spatial relations is required. In clinical practise, the traditional method to examine complex cases of extreme spinal stenosis and herniated intervertebral disks requires the injection of contrast dye into the spinal subarachnoid space (x-ray myelography). This is an invasive and time-consuming procedure that comes with a considerable risk for the patient.To these ends an alternative examination method based on an highly optimized MRI sequence was developed by Dr. Knut Eberhardt at the Division of Neuroradiology. For the visualization of the data we again propose a fast sequence of simple image-processing operations for a coarse separation of anatomical structures similar to the visualization of dural arteriovenous fistulae described in the previous chapter.
