Clinical significance of anterior high-intensity zones in lumbar discs


  • Presence of anterior high-intensity zones (HIZs) on lumbar magnetic resonance (MR) images is associated with low back pain.

Why this matters ?

  • HIZ lesions in the posterior annulus of lumbar discs are considered reliable markers of internal disc disruption, but the clinical significance of anterior HIZ lesions has not been determined.

  • Recognition that anterior HIZ are associated with lower back pain might help to improve identification and management of people with intervertebral disc degeneration.
