    PurposeTo identify anterior spinal artery (ASA) infarct or occlusion by CT angiography (CTA) in patients with cervical spondylotic myelopathy (CSM).MethodsFourteen patients with CSM were performed CTA of ASA after admission. T2-weighted hyperintensity of MR image was compared with image of CTA of ASA.ResultsAll patients presented spinal canal sagittal diameter compression from 10 to 80% and different T2-weighted hyperintensity of MR images. No ASA infarct or occlusion was found in CSM patients.ConclusionASA infarct or occlusion is not commonly seen in CSM patients with spinal canal sagittal diameter compression less than 80%. Pathological changes about T2-weighted hyperintensity of MR image in CSM have no close correlation with ASA infarct.
