Objective: To assess changes in perfusion parameters of the spinal cord before and after the decompression surgery for cervical spondylotic myelopathy.

Methods: Fourteen patients with a spondylotic myelopathy were included. The mean transit time (MTT), bolus arrival time (T0), and time to peak (TTP) were obtained from regions of interest (ROIs). Data were assessed in a ratio between parameters from the spinal cord and that from the pons (MTT index = MTT ROI / MTT pons, T0 index = T0 ROI / T0 pons, TTP index = TTP ROI / TTP pons). Patients group was divided into two according to percent recovery rate (A) on neurosurgical cervical spine scale (NCSS).

Results: MTT index in the patients of good recovery (>50%) showed significant reduction. T0 index and TTP index revealed no significant change between the surgeries in both groups.

Conclusions: Reduction in MTT index can predict the improved perfusion of the spinal cord following surgery for cervical spondylotic myelopathy.
