Abstract：Objective To investigate the diagnostic value of 320-row CT angiography (320-CTA) for the diagnosis of spinal vascular malformations(SVMs).Method Twenty patients with SVMs indicated by 320-CTA underwent digital subtraction angiography (DSA)a week after 320-CTA.The outcomes of 320-CTA were compared with those of DSA in 16 patients.Result Of 16 patients with SVMs receiving both 320-CTA and DSA, 10 patients, including 2 patients with inner-medullary arteriovenous malformations (IMAVMs),3 with peri-medullary arteriovenous fistula(PMAVFs)and 5 with spinal dural arteriovenous fistula(SDAVFs),had similar diagnoses made by 320-CTA and DSA and 6 had different diagnoses, including 2 in whom the feeding arteries and lesions extent displayed by 320-CTA were not consistent with those displayed by DSA,3 with SDAF in whom the feeding arteries were not displayed by 320-CTA and DSA showed no abnormal vessels in 2 and 1 with cavernous sinus dural arteriovenous fistula diagnosed by DSA in whom IMAVM was suspected by 320-CTA.Conclusion It is suggested 320-row dynamic CT is a valuable method to screen out SVMs, but the small feeding artery is sometimes ignored by 320-CTA, and the misdiagnosis of vascular malformation may be induced by 320-CTA due to limited scanning range.
