Abstract:
Objective To compare the clinical diagnostic value of 320 row four-dimensional CT angiography (4D-CTA)and digital subtraction angiography (DSA)in untreated arteriovenous malformation (AVM)patients.Methods Thirty-six patients with AVM diagnosed by DSA were included in this study.Two independent readers blind to the results of all examinations evaluated the find-ings of DSA and 4D-CTA of each patient.All results were then documented using a standardized scoring sheet.Results The diagno-sis results of 4D-CTA for AVM lesions in all 36 patients were accurately consistent with those of DSA,including the position,size and vascular structure.There were 14 cases with the largest diameter <3 cm,20 cases 3-6 cm,2 cases >6 cm.Lesions involved only the anterior circulation in 13 cases,only the posterior circulation in 13 cases,and both the anterior and posterior circulation in 10 cases.Conclusion 4D CTA has excellent diagnostic accuracy in the detection of AVM lesions,including size,location,feeding ar-teries and draining veins,with similar value as DSA in the clinical diagnose and evaluation of AVM.
