Abstract Objective: To evaluate the clinical value of 640-slice spiral CT angiography(CTA) and 3.0T dynamic MR angiography(CE-MRA) in the diagnosis of spinal vascular malformations. Methods: Nineteen cases of clinically suspected spinal vascular disease patients, including 11 cases with CTA examinations, 10 patients with CE-MRA examination, 16 with DSA treatment and 3 with surgery were studied. Results: Four of the 11 cases with CTA examinations were SDAVF, 4 were PMAVF and 2 were SCAVF. Eight were consistent with the DSA diagnosis, and the DSA of one case was negative. Seven of the 10 cases with MRA examinations were SDAVF, in 2 of which CTA examinations did not display the artery and the fistula, but CE-MRA showed the artery and the fistula well. Two cases were PMAVF and 1 case was SCAVM, all consistent with the DSA diagnosis. Conclusion: 3.0T CE-MRA is better than CTA in displaying the spinal vascular malformations artery and fistula, and in diagnosing of spinal vascular malformations. CTA spinal angiography has a great value in the diagnosis of the spinal vascular malformations, and can be used as a screening examination prior to the DSA to guide the DSA. While 3.0T CE-MRA can display the spinal vascular malformations artery and fistula quickly, noninvasively and clearly. CTA and CE-MRA are of great value in diagnosing the spinal vascular malformations, in assisting determining the treatments and in the follow-up visits, etc.
