Materials and methods We retrospectively reviewed the spinal MRI findings of 25 patients with vascular malformation in spinal canal (14 male,11 female,age range 5 - 56 years old). The diagnosis were established by MRI and proved by pathology and partly by angiography. Results Among the 20 cases of arteriovenous malformation(AVM)in this series,MRI detects a specific flow void appearance in spinal canal. Conclusion MRI may represent the best modality for the screening of patients suspected with vascular malformation in spinal canal,it is the first choice of method in the diagnostic examination of the disease.展开更多
