Prognosis significance of focal signal intensity change on MRI after anterior decompression for single-level cervical spondylotic myelopathy

摘要

Objective The prognosis significance of signal intensity changes remains controversial, and several reports showed that focal-increased signal intensity is of little significance in prediction of the surgical outcome after the treatment of cervical spondylotic myelopathy (CSM). The purpose of this study was to investigate whether focal ISI can help assess the prognosis in patients with single-level CSM by means of measuring the ratio of T2/T1 signal intensity.
