Lumbar Spine Disorders:

Use of MR Neurography for Diagnosis of

Routine and Unusual Spinal Pathologies
A) 59 year old woman with persistent severe left  S1 radiculopathy exacerbated by lumbar spine instrumented fusion and not relieved by subsequent removal of the instrumentation. The image demonstrates perforation of the left S1 root by the course of the pedicle screw (ps). No further surgical treatment was recommended.

(B) Persistent sciatica after a fall with no improvement after discectomy. The image demonstrates inflammation around the nerve (S1) consistent with a sacral fracture (fx) abutting the foramen.

C) The MR Neurography imaging protocol results in an MR myelogram as well as Neurographic images of the exiting nerve roots.
