Comparative Study on Multislice CT Angiography and Digital Substraction Angiography in Diagnosis of Intracranial Aneurysm / 实用放射学杂志

ABSTRACT

Objective To evaluate the value of multislice spiral CTA in diagnosis of intracranial aneurysm.Methods CTA data in 32 patients with intracranial aneurysms proved by operation and DSA were retrospectively analysed in comparison with the results of DSA.Results 38 aneurysms in 32 patients were detected by DSA and operation.Six cases of 32 had two aneurysms.36 and 34 aneurysms were detected by DSA and CTA respectively.4 aneurysms located at anterior communicating artery,7 at middle cerebral artery,9 at posterior communicating artery,14 at internal carotid artery and 4 at basilar artery.Conclusion MSCTA can be used as the method in screening intracranial aneurysms for surgery and interventional therapy.
