Magnetic Resonance T2 Image Signal Intensity Ratio and Clinical Manifestation Predict Prognosis After Surgical Intervention for Cervical Spondylotic Myelopathy

Abstract

Patients with low SI ratio who were not too old and had a shorter duration of disease experienced a good surgical outcome. However, with the increase of SI ratio and the occurrence of pyramidal sign, a poor prognosis after surgery will show. SI ratio and clinical manifestation can be a predictor of surgical outcome.
