Comparison of axial and sagittal spinal cord motion measurements in degenerative cervical myelopathy

Background and Purpose The timing of decision‐making for a surgical intervention in patients with mild degenerative cervical myelopathy (DCM) is challenging. Spinal cord motion phase contrast MRI (PC‐MRI) measurements can reveal the extent of dynamic mechanical strain on the spinal cord to potential...

Description
Summary:Background and Purpose The timing of decision‐making for a surgical intervention in patients with mild degenerative cervical myelopathy (DCM) is challenging. Spinal cord motion phase contrast MRI (PC‐MRI) measurements can reveal the extent of dynamic mechanical strain on the spinal cord to potentially identify high‐risk patients. This study aims to determine the comparability of axial and sagittal PC‐MRI measurements of spinal cord motion with the prospect of improving the clinical workup. Methods Sixty‐four DCM patients underwent a PC‐MRI scan assessing spinal cord motion. The agreement of axial and sagittal measurements was determined by means of intraclass correlation coefficients (ICCs) and Bland‐Altman analyses. Results The comparability of axial and sagittal PC‐MRI measurements was good to excellent at all cervical levels (ICCs motion amplitude: .810‐.940; p
