3D DCE-MRA in spinal vascular malformations

Purpose: This study was carried out to investigate whether 3.0T dynamic enhanced 3 dimensional magnetic resonance angiography (3D DCE-MRA) could identify spinal cord vascular malformations efficiently. Material: and Methods: 32 suspected cases of spinal vascular disease with MR imaging and clinical symptoms were detected using DCE-MRA. 28 patients were valued through DSA for 3-5 days, and surgical treatment was performed on 24 patients. Results: : DCE-MRA was used to examine all the cases which recognized abnormal vascular lesions clearly, and 28 cases were consistent with DSA or surgical diagnosis. The arterial blood supply was evaluated accurately in 28 cases. The findings were correct in 26 cases. Conclusion: 3.0T DCE-MRA features high sensitivity and accuracy in detecting and characterizing SVMs, especially SDAVF.
