What does L3-4 spinal stenosis grossly unchanged mean?

L3-4 spinal stenosis grossly unchanged means that there is no significant change in the narrowing of the spinal canal at the level of the L3-L4 vertebrae. This can be seen on an MRI or CT scan. Spinal stenosis is a condition in which the spinal canal is narrowed, putting pressure on the spinal cord and nerves. This can cause pain, numbness, and weakness in the back, legs, and arms.
