High reliability between low-field, high-field MRI seen for features of lumbar disc degeneration

April 24, 2015

Researchers found excellent reliability between low-field and high-field MRI for disc herniation type and severity, central canal and lateral recess stenosis, and foraminal stenosis among patients with degenerative disease of the lumbar spine.

A total of 100 patients (mean age: 56.3 years) with neurogenic claudication or sciatica underwent low-field (0.25 T) and high-field (1.5 T or 3 T) MRI scans of the lumbar spine for the study. Using established, reliable grading systems, two radiologists evaluated patients’ intervertebral disc herniation; central canal, lateral recess and exit foraminal stenosis; and nerve root compression at L3-L4, L4-L5 and L5-S1 for both low-field and high-field systems.
