Application of Lumbar Prone MRI in Patients with Low Back Pain and Difficult-to-treat Radiculopathy
Objective This study was designed to evaluate the application of lumbar prone MRI in patients with low back pain and difficult-to-treat radiculopathy,in order to provide reference for clinical diagnosis and treatment.Methods Nineteen patients with chronic moderate-to-severe LBP and/or root pain that did not respond to conventional or interventional therapy were included in the study.Magnetic resonance imaging in both supine and prone positions was analyzed by a specialist to record MRI features in both supine and prone positions,including spinal canal area,lateral recess diameter,foramen area,and thickness of ligamentum flavum.3D MRI reconstructions of different pathological patterns were created.Results The average pain score of patients was 6.5(R:4-8).In 52.6％of cases,disc lesions/increased lesions with significant flexion and thickening of the ligamentum flandum were seen only on prone MRI,which was not seen on supine MRI.In 26.3％of cases,there was no significant vertebral stenosis on MRI in supine position,but there was in prone position.Conclusion Four pathological changes were found in prone MRI,but not in supine MRI.Prone MRI can be an important supplement to conventional supine MRI.
