dc.description.abstractObjective and Background: To study the efficacy of lumbar (AL) magnetic resonance imaging (MRI) in patients with suspected lumbar spinal stenosis (LSS), with and without AL compression. Supine MRI is used in the assessment of patients with LSS. However, MRI findings may poorly correlate with neurologic findings because of the morphologic changes of the lumbar spinal canal between upright standing and supine positions. In patients without significant stenosis in routine lumbar MRI, by applying AL, MRI can show significant LSS. Methods: This study included 103 consecutive patients (188 disc levels) who presented with neurogenic claudication with and without low back pain. AL was performed using a nonmagnetic compression device for 5 minutes. T1- and T2-weighted axial and sagittal sequences were obtained during AL applied to the spine. The dural sac cross-sectional area (DSCA) appeared to be narrow at each disc level of L4–5 to L5–S1 in all patients and was measured using T2-weighted images in routine supine and AL images. Results: The groups included patients with a reduction in the DSCA (>15 mm2) according to patient age and DSCA in routine spine MRI. The mean DSCA of the disc levels without and with AL were 138 mm2 and 123 mm2, with a mean difference of 15 mm2 at L4–5, 134 mm2 and 125 mm2 and a mean difference of 9 mm2 at L5–S1, respectively. conclusions: The use of AL MRI in patients with clinically suspected LSS could reduce the risk of misdiagnosis of stenosis, leading to inappropriate treatment. © 2019 Elsevier Inc.
