How to Read a MRI of Lumbar Degenerative Spondylolisthesis and Spinal Stenosis

here's a side view of an MRI of a patient withsubstantial degenerative changes and a degenerative Spondylolisthesis Stenosisor slip at four five and the central canal is also blocked and that is called spinal stenosis again reading this MRI we see the spinal cord here which endsthere and the nerve roots which come out

of the spinal cord again the white is cerebral spinal fluidwhich is water we see again the vertebra we see again the discs these discs here are quite degenerative and if we look carefully we're going tosee that this L four vertebra has slid forward on L five that slip

is called a degenerative Spondylolisthesis and we can look at the spinal canal and see the spinal canal in this area his clogged up essentially and quitenarrowed and that is deleterious to the nerves we can look at this with a topdown viewand again the yellow line here is where we're making our cut here's the spinal canal we can see allof the nerve roots here

we look at the facets before these aredegenerative facets and if we march up the spine and watchthe size of the canal will see that the canal narrowssubstantially right here and literally the contents of the entirespinal canal are in this tiny little triangular area as soon as we pass that level up thespinal canal becomes normal size and the nerves spread out like they weredesigned to spread out so this particular patient right here atthe four five level has severe spinal

stenosis because one vertebra has slid forward onthe other compressing the nerve substantially atthat level.
