   A Focused Review
   Joseph D. Fortin, DO, and Michael T. Wheeler, DO.

Lumbar spinal stenosis is a commoncondition seen in patients presenting to physicianswho specialize in pain managementor erform spine surgery. The designationof “spinal stenosis” without other qualifiers vague and as such holds little practical value. Classifications have been created in order to more specifically describe the various etiologiesas well as the site(s) of arrowing. For this purpose, diagnostic imaging studies arevital. These include myelography, computed tomography (CT), and magnetic resonance imaging (MRI). Each imaging modality has its own inherent advantages and limitations in demonstrating anatomical structures and how they may contribute to the stenotic process. Since proper treatment follows accurate identification of the pathology, it is important for physicians to have a sound understanding of normal and abnormal spinal elements as they are depicted on various imaging studies.
