This literature review examines the contemporary status of radiological diagnosis concerning isolated and combined stenosis of the cervical and lumbar spinal canal. Degenerative isolated and combined stenosis are prevalent spinal pathologies. The narrowing of the spinal canal is mainly a result of various pathogenic processes affecting the bony and soft tissue components of the spine, occurring due to agerelated and static wear and tear. These degenerative processes may affect single or multiple spinal segments within the cervical and lumbar regions.
