Summary

This review covers diagnosing lumbar radiculopathy and spinal stenosis. Imaging recommendations include plain X-rays initially, followed by MRI, with CT or myelogram reserved for specific cases.

Area of Science:

  • Neurology
  • Radiology
  • Orthopedic Surgery

Background:

  • Lumbar radiculopathy and spinal stenosis present diagnostic challenges.
  • Accurate imaging is crucial for effective treatment planning.

Purpose of the Study:

  • To review the diagnostic approaches for lumbar radiculopathy and spinal stenosis.
  • To outline the role of various imaging modalities in evaluating spinal stenosis.

Main Methods:

  • Review of differential diagnosis for lumbar radiculopathy.
  • Analysis of clinical presentations of spinal stenosis.
  • Evaluation of pathological anatomy and roentgenographic considerations.
  • Assessment of imaging sequences: plain roentgenograms, MRI, CT, and myelography.

Main Results:

  • Plain roentgenograms are recommended first for suspected spinal stenosis to exclude other lesions and assess disc/foraminal narrowing and deformities.
  • MRI is the preferred next step, often obviating the need for myelography or CT.
  • Myelography or CT may be necessary in select cases where MRI is contraindicated or inconclusive.

Conclusions:

  • A stepwise imaging approach, starting with plain roentgenograms and progressing to MRI, is effective for evaluating spinal stenosis.
  • Advanced imaging like CT or myelography should be reserved for specific clinical scenarios.
  • Understanding the differential diagnosis of lumbar radiculopathy aids in the comprehensive evaluation of spinal stenosis.
