Implication

A retrospective observational study evaluates axial loaded MRI's effectiveness in diagnosing lumbar spinal stenosis, highlighting its importance in clinical decision-making.

Key Points

  • This research aims to assess the diagnostic accuracy of axial loaded MRI in patients showing symptoms of lumbar spinal stenosis despite inconclusive conventional MRI findings.
  • Retrospective observational study design.
  • Patients with suspected lumbar spinal stenosis and inconclusive cMRI underwent additional axial loaded MRI.
  • Disk levels between L3 and S1 were assessed for changes in various types of stenosis and dural sac area.
  • Central canal stenosis grade improved from A/B to C/D in 30.8% of cases.
  • Lateral recess stenosis changed with confirmed nerve root compression in 13.9%.
  • Dural sac area decreased below 75 mm² in 18.1% of cases.
  • Foraminal stenosis showed changes with nerve root compression in 4.6% of foramina examined.
