The ability of diagnosing lumbar radiculopathy has improved because of the sophisticated imaging techniques. Magnetic resonance imaging (MRI) is a diagnostic tool that is superior to computed tomography (CT) in visualizing soft tissues, like spinal cord and nerve roots. The supplemental information regarding to nerve function and muscle injury can be provided by using electrodiagnostic testing.
