ABSTRACT
Objective To explore the value of CT spinal angiography with 256 MSCT and fast dynamic contrast-enhanced 3D MR angiography (CE-MRA) at 3.0 T in the diagnosis of spinal vascular malformations by comparing with results of DSA and operation.MethodsSeventeen patients suspected of spinal vascular diseases by initial MR and clinical manifestations all underwent CT spinal angiography.Of them,10 patients underwent MRA,15 patients underwent DSA within 3-5 days,and 8 patients finally underwent surgical treatment.ResultsCTA examination clearly showed the abnormal vascular lesions in 16 of 17 cases,including 7 cases with the diagnosis of spinal dural arteriovenous fistula,7 cases of perimedullary arteriovenous fistula,and 2 cases of spinal arteriovenous malformations. The results were consistent with the diagnosis of DSA or surgery.One case was poorly diagnosed.The feeding vessels were correctly determined in 12 cases,and the level of fistulas were correctly displayed in 12 cases.The level of fistulas and feeding vessels were accurately showed in 7 of 10 cases with MRA,while the other 3 cases exhibited normal with DSA.ConclusionsSpinal angiography with 256 MSCT and CE-MRA at 3.0 T can clearly show the extent of spinal vascular malformations,feeding arteries and fistula location.They are safe,noninvasive,convinient and can shorten the time of DSA diagnosis and treatment.They play an important role in diagnosis and treatment of spinal vascular malformations and postoperative follow-up.
