Cervical spondylotic myelopathy (CSM) is the most common cause of non-traumatic spinal cord injury and spinal cord dysfunction in the elderly. It is a progressive disease that worsens over time if left untreated. Early diagnosis and treatment can help slow the progression of CSM and improve symptoms. Radiologic imaging modalities are widely used in the diagnosis and management of this disease. This review aims to provide an understanding of the use of radiologic imaging modalities in the evaluation of functional and morphologic changes in the central nervous system in CSM.
