ABSTRACT
Objective The purpose of this study is to explore the clinical value of CT angiography( CTA) in the diagnosis of multiple intracranial aneurysms.Methods The data of CTA and DSA from 74 patients with multiple intracra-nial aneurysms from July 2011 to March 2015 were reviewed retrospectively.Results One hundred seventy-seven aneu-rysms were detected by DSA, and 175 aneurysms were detected by CTA.Among the aneurysms identified by CTA, 4 aneu-rysms were false positive and the correct detection rate of CTA was 96.6%.One hundred sixty-five aneurysms identified by CTA were confirmed by DSA and the correct diagnostic rate of CTA was 96.5%.CTA failed to detect 6 aneurysms and mis-diagnosed 10 aneurysms.Conclusions The correct detection rate and diagnostic rate of CT angiography ( CTA) in multiple intracranial aneurysms is relatively high.But previous surgery, spasm of the vessels, the size and number of aneurysms, radiologists'experience can influence the accuracy of ( CTA) in the diagnosis of multiple intracranial aneurysms, indicating that we should combine CTA with DSA to avoid the misdiagnosis and missed diagnosis.
