- Abstract: Objective To explore the application of multi-slice CT angiography(MSCTA)in the diagnosis of cerebral aneurysm(CA),and to analyze its imaging characteristics.Methods A total of 180 patients with suspected CA in the First Affiliated Hospital of Nanjing Medical University were enrolled,and all these patients underwent digital subtraction angiography(DSA)and MSCTA.Taking DSA results as the golden standard,the consistency of MSCTA in the diagnosis of CA was evaluated.The diagnostic coincidence rate of CA distribution,the maximum diameter of tumors and maximum width of tumor neck by the two methods were compared.Results In the 180 patients with suspected CA,DSA showed that there were 174 confirmed cases,including 240 aneurysms,while MSCTA showed that there were 168 confirmed cases,including 207 aneurysms.Taking DSA results as the golden standard,the sensitivity,specificity,accuracy and Kappa value of MSCTA in the diagnosis of CA were 96.55%,100%,96.67%and 0.651 respectively,showing good diagnostic consistency.The diagnostic coincidence rates of CA distributed in the internal carotid artery,vertebrobasilar artery,middle cerebral artery,clinoid process of internal carotid artery,cavernous sinus segment of internal carotid artery,anterior communicating artery and posterior communicating artery diagnosed by MSCTA were 81.82%,83.33%,85.71%,87.50%,86.67%,90.00%and 90.00%,and the overall diagnostic coincidence rate was 86.25%.There was no significant difference in the maximum diameter of tumors or maximum width of tumor neck between MSCTA and DSA(P>0.05).Conclusion The diagnostic value of MSCTA for CA is good,whihc has high diagnostic consistency with DSA and can be widely used in clinic.
