Methods A total of 40 case of AVM were examined with imaging methods in which 19 MRI, 30 CT and, 12 DSA. Combination of two or three kinds of eximinations were perfo rmed in 20 and 4, respectively. Results Diagnostic accordance r ate rate of CT was 70%, sensitivity and specificity of MRI were 100% and 84% res pectiv ely, diagnostic accordance rate of DSA was 92%. Conclusion MRI,CT,D SA can play important roles in the diagnosis of AVM. MR and DSA are superior to CT. DSA could reveal the circulation time and the stealing blood situation of AV M and thus suggests the applicability of interventional embolization therapy.
