Socioeconomic Aspects of Spinal Imaging: Impact of Radiological Diagnosis on Lumbar Spine-Related Disability

Low back pain presents a difficult problem for patients and their doctors. The symptom affects the majority of people at some point in their lives and usually has a benign natural history. However, as a society, we consume tremendous resources to diagnose and treat painful spinal disorders. Magnetic resonance imaging (MRI) facilitates the "medicalization" of low back pain due to its exquisitely sensitive depiction of pathoanatomy. Unfortunately, many of these findings are present in normal subjects. Radiologists should recognize the poor correlation between MRI findings and significant, treatable disease and support the use of evidence-based guidelines for patient referral. MRI studies should be interpreted stringently, to avoid unnecessary patient labeling and potentially inappropriate treatment.
