Correlation of lumbar lateral recess stenosis in magnetic resonance imaging and clinical symptoms

Figure 1 Axial T2-weighted magnetic resonance image of lumbar level L4/5 shows the lateral recess that is bordered laterally by the pedicle, posteriorly by the superior articular facet, and anteriorly by the vertebral body, endplate margin, and disc margin.

Figure 2 Axial T2-weighted magnetic resonance images illustrate the grading system of lateral recess stenosis. A: Grade 0 bilaterally; B: Grade 1 bilaterally; C: Grade 2 bilaterally; D: Grade 3 on the left, Grade 1 on the right.
