Sensory Level and Neuro-Imaging
In theory, a sensory level noted after spinal cord injury should be a guide to the spinal segment involved (one or two above the level).
I have had to doubt the sensitivity of this clinical finding in determining the MRI request (Lumbo-scaral or Thoraco-Lumbar) when faced with paraparesis (especially flaccid).
Is this purely a reflection of my incompetence.. or is it a common problem?
Are there more definite features to look for so that one does not have to "guess"..?
I'll really appreciate some help here.
p.s. MRI is not a very cheap study where I work and missing the lesion just because one wasn't certain where to image is certainly not good news...
