Imaging of the Aging Spine.

Degeneration of the spine is a normal aspect of aging. The associated changes of spine degeneration seen on imaging are typically asymptomatic. However, distinguishing normal age-related change from symptomatic pathologic change can be challenging owing to the overlap in imaging features. Understanding the general prevalence, timing, and evolution of age-related change can aid in this differentiation and help prevent imaging overdiagnosis and unnecessary workup.
