Abstract

Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction and is caused by static or dynamic repeated compression of the spinal cord resulting from degenerative arthritis of the cervical spine and some biological injuries to the cervical spine. The T2 signal change on conventional magnetic resonance imaging (MRI) is most commonly associated with neurological deficits. Diffusion tensor imaging and MR spectroscopy show altered microstructure and biochemistry that reflect patient-specific pathogenesis and can be used to predict neurological outcome and response to intervention. Functional MRI can help to assess the neurological functional recovery after decompression surgery for CSM.

Keywords: Cervical spondylotic myelopathy, Magnetic resonance imaging, Diffusion tensor imaging, Magnetic resonance spectroscopy, Functional magnetic resonance imaging

Core tip: This article attempts to investigate the application of magnetic resonance (MR) technology to the management of cervical spondylotic myelopathy (CSM) patients and discusses recent and future advances in both conventional and novel MR techniques. The novel MR techniques, including diffusion tensor imaging, MR spectroscopy and functional MR imaging, have all played an essential role in the management of patients with CSM.
