69-Year-Old Man With Midline Low Back Pain (IMAGE)
Caption
The patient denied buttock pain, leg pain, and symptoms of spinal claudication. Axial unenhanced fast-spin echo T2-weighted (TR 2800, TE 80) MRI shows severe canal stenosis and severe bilateral facet joint degeneration with bony remodeling. In research arm 1, radiologists reviewed lumbar spine images with symptom information obtained from patient questionnaires and diagnosed facet joint degeneration as the presumptive pain generator. In research arm 2, radiologists reviewed lumbar spine images without symptom information and diagnosed canal stenosis as the presumptive pain generator. In research arm 3, the MRI report listed canal stenosis as the presumptive pain generator.
