L1–L2, L2–L3 intervertebral discs
moderate confidenceMild disc bulging and loss of normal disc height signal.
Sagittal MRI of the lumbar spine shows multilevel degenerative disc disease with posterior disc protrusion or bulge at L4–L5, which is the most significant finding as it narrows the central spinal canal and indents the posterior thecal sac.
Severity reflects the AI reading's own wording — it is not a diagnosis, and not your radiologist's opinion.
