The results showed that severity of MSCC, bleeding and cord swelling were key indicators of a poor prognosis after SCI. Conversely, the absence of these symptoms indicated a good chance for neurological recovery even if the injury otherwise appeared severe.

"Since the severity of spinal cord compression is a predictor of outcome after SCI, this study suggests that MRI may predict which patients would benefit the most from decompressive surgery," Dr. Fehlings said.

He added that MRI should be performed on all patients with acute SCI whenever feasible as it provides information with prognostic value and serves to guide the clinician to optimize clinical care.
