Abstract:
Objective To evaluate the accuracy and clinical efficacy of low field phase-contrast magnetic resonance angiography(PC-MRA),CTA and 3D-DSA in the diagnosis of cerebrovascular disease.Methods 70 patients with clinically suspected cerebrovascular diseases were examined with PC-MRA,CTA and 3D-DSA.The sensitivity in detecting the cerebrovascular disease with these three methods were compared.Results Fifty-one patients were detected with cerebrovascular diseases in seventy patients by three imaging methods,including 36 aneurysms in 33 cases and 18 arteriovenous amlformations.33,34 and 35 aneurysms,17,16 and 18 arteriovenous malformations were detected by PC-MRA , CTA and 3D-DSA respectively , the sensitivity were 91.67% and 94.44%,94.44% and 88.89%,97.22% and 100% respectively.There were no significant difference in the sensitivity of detecting aneurysm and arteriovenous malformation between these three imaging methods(P>0.05).Conclusion PC-MRA,CTA and 3D-DSA are no of difference in diagnosis of cerebrovascular malformation.
