What does L3-4Moderate bilateral neural foraminal narrowing secondary to degenerative diffuse disc bulge and degenerative facet joints. No central canal spinal stenosis mean?

The phrase describes findings from an imaging study of the lumbar spine, specifically at the L3-L4 level. "Moderate bilateral neural foraminal narrowing" indicates that the openings through which the spinal nerves exit the spine are narrowed on both sides, potentially causing nerve compression. This narrowing is attributed to a degenerative disc bulge and changes in the facet joints, which are part of the spinal structure. Importantly, "no central canal spinal stenosis" means that the central spinal canal, which houses the spinal cord, remains open and is not narrowed.
