| 摘 要： | 目的 评价CT、MBI及DSA对脑动静脉畸形（AVM）的诊断价值。方法 40例AVM行MRI检查19例，CT检查30例，DSA检查12例，同时完成2项或3项检查者分别为20例和4例，结果 CT诊断率70%，MRI敏感性和特异性分别为100%和84%，DSA诊断率92%，结论 MRI、CT、DSA对AVM诊断均有重要价值。而MRA和DSA优于CT，DSA反映AVM循环时间和盗血情况，并可实施介入栓塞治疗。

| Abstract: | Objective To evaluate the diagnostic value of MR I、CT、DSA for cerebral arteriovenous malformation(AVM). 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. |
