we're now going to discussa patient with a
cervical herniated disc herniated disc in the neck
and this person ended up having some spinal cord injury because of it
so on this side view MRI we saw on the normal one
again brain is up here
this is the spinal cord coming down through here again the white stuff
cerebral spinal fluid
these are the vertebra
and again these are the discs
we can look down at the C five six disc here and we can see that there is a
disc herniation back here you can see it's compressing the spinal cord
and that spinal cord compression is causing this patient some symptoms of a
condition called myelopathy or spinal cord dysfunction
we can see the cord itself has a uniform color until we get here where
we can actually see some increased white or signal change within the cord which is
an indication of some problems with the cells within the cord
we can look at it from the top down view and again this yellow line shows us
where this cut is and this is normal here you can see the spinal cord
surrounded by the csf with the nerve exit zones and as we march down the
we continue to see that the spinal canal is nice and wide open there's still
plenty of cerebral spinal fluid around the cord up until the point that we get
to the injury
where we can see the herniation is causing significant deformation of the
spinal cord and if you look carefully you can see this white area in the cord
and if we go down to the level right below
the herniation
you can see the white area over the cord injury level
within the cord at the level below but this is the level of the herniation
that is causing that compression
this is a stir image of the spinal cord
this is very similar to the T two image that we saw where the water was white
you'll see with this stir image the water is still white
but the fat back here and the fat in the bones is suppressed
it allows us to see inflammation with a better vantage point
and again if you follow the spinal cord
and you see where the injury is you can see all of the edema in the cord because
of this herniated disk compressing the cord
this is a comparison of the injury cervical spine to a normal cervical
in a normal cervical spine you can see the spinal cord is free
all the way down
there is white csf on either side and this white signal of the cord which you
don't have at the normal level
