An analytical study of mri signal changes as a prognostic predictor in patients underoing cervical corpectomy

Introduction: Cervical Corpectomy is a rewarding surgery for Cervical compressive Myelopathy. Increased signal intensity in T2 weighted MRI indicates significant prognosis. Materials and Methods: About 100 patients of cervical compressive myelopathy, who underwent cervical corpectomy, from June 2014 to June 2018 at "The Institute of Neurosurgery, Madras medical College, Chennai, were retrospectively studied. Pre-operative MRI signal changes and post operative functional outcome by Nuricks grade were analysed. Results: Increased signal intensity is seen in about 83 patients. T1 weighted MRI signals does not carry significance. Increased signal intensity in T2 weighted MRI is an independent predictor of functional outcome. Conclusion: Pre-operative T2 weighted signal changes helps to assess the postsurgical outcome following cervical corpectomy. Subject Area: Neurosurgery.
